[GENERAL] Inheritance vs. LIKE - need advice
Dear pgsql-general moderators, I sent this post out over the weekend. Is there a reason why it is not getting posted to the list? Many thanks for your assistance. I really need some advice on this issue from people with experience using both inheritance mechanisms in PostgreSQL. Cheers, Bill Bug Hi All, Sorry to bring up the topic of PostgreSQL inheritance again, but after going through the archives and Google results, I still don't have a clear sense of whether my plan to implement a schema I'm working on is the preferred way to go. First, I'd like to find out if the way I'm thinking about Inheritance vs. the SQL DDL CREATE TABLE modifier LIKE is correct. The simplest analogy I can think of from OO techniques is PGSQL Inheritance corresponds to Class Inheritance, while LIKE is more like an inheritable Interface (Java) or Mixin (Ruby). Inheritance maintains strict hierarchical relationships propagating the "Class" identity down through to all progeny. LIKE on the other hand simply provides a means to re-use a set of fields in an unlimited number tables without having to redefine those fields for each table you use them in. This view is incomplete and far from a perfect fit to the way PGSQL Inheritance & LIKE work, but I think it's a helpful way of thinking of these 2 related mechanisms, when trying to decide how and when to use them in their current form. As has been mentioned many times in posts here, as well as in the PGSQL docs, PGSQL Inheritance is only partial. Table fields are propagated as well as the group identity, but no other RDBMS objects created on the parent ( INDEXES, CONSTRAINTS & SEQUENCES primarily) are inherited. As has been endlessly stated in posts here and elsewhere, this is a significant short-coming for the PGSQL Inheritance mechanism which those of us desirous of using Inheritance would love to see fixed (I understand it has been on the TODO list for many years, as this mechanism has been in the PGSQL code base for over 15 years). I don't agree this makes PGSQL Inheritance unusable. There are situations where I think it can still be useful, and I describe one below. I'd welcome feedback on that opinion, however, as I'd hate to have my relative ignorance doom the data schema I'm about to fill with a few million rows of data to serious problems later. The following is an example of using both Inheritance and LIKE in the context described above. CREATE TABLE curation_info ( created_by TEXTNOT NULL, create_date TIMESTAMP WITH TIME ZONE, modified_by TEXTNOT NULL, mod_date TIMESTAMP WITH TIME ZONE ); CREATE TABLE book ( id_pkSERIALPRIMARY KEY, titleTEXTNOT NULL, author_id_fkINTNOT NULL, publisher_id_fkINTNOT NULL, pub_year DATENOT NULL, total_pages INTNOT NULL LIKE curation_info ); CREATE TABLE novel ( id_pkSERIALPRIMARY KEY, genre_id_fkINTNOT NULL ) INHERITS (book); CREATE TABLE textbook ( id_pkSERIALPRIMARY KEY, subject_id_fkINTNOT NULL ) INHERITS (book); CREATE TABLE publisher ( id_pkSERIALPRIMARY KEY, nameTEXTNOT NULL, address_id_fkINTNOT NULL, LIKE curation_info ); CREATE TABLE author ( id_pkSERIALPRIMARY KEY, last_name TEXTNOT NULL, first_name TEXTNOT NULL, middle_name TEXTNOT NULL, address_id_fkINTNOT NULL, LIKE curation_info ); This is not the best way to model book info (for instance, books are only allowed to have 1 author in this schema), but it will help me to make my point. Books, novels and textbooks will be considered equivalent in the context of many queries. At the same time, there will be other queries where it will be important to consider novels & textbooks as distinct entities. The PGSQL Inheritance mechanism easily supports both of these situations. The curation fields listed in the 'curation_info' table are found ubiquitously in tables throughout many data schema. However, it is not likely there would be a circumstance where you would want to consider all tables containing these fields "curatable entities" to be queried as a group. That simply makes no sense. In this case, LIKE seems to be the best way to propagate these fields, since it doesn't couple all tables containing them to the parent 'curation_info' table. As I see it, there are at least 3 major problems with adopting such a schema - despite the obvious efficiencies it offers (most of which have been reported elsewhere): 1) none of the parent table ('book') CONSTRAINT

For one, it's all in memory, so be prepared to have several machines with lots and lots of RAM. The Mysql docs for 5.0 cover it quite well. Watch out for its wastefulness though. It does things like reserve space based on the max size of a field, so if you have a varchar(250), then every row in the database will have 250 bytes of space allocated, even if you only use 1. At least, that's how it was documented the last time I looked at it.

It could be that it's evicting unrelated dirty pages from cache (although PG 8.0 is supposed to try to avoid doing that during a simple seqscan). Another theory is that the table has a whole lot of recently-changed rows, and the writes are a side effect of the SELECT setting commit hint bits to tell future transactions what it found out about the commit status of the rows. I dunno what procinfo is --- personally I would use strace and see exactly which file(s) the database processes are issuing writes against.

There are a lot of platforms where libc thinks that IPv6 sockets exist but the kernel doesn't agree, and the above is the expected result in such cases. The postmaster will try to bind to the IPv6 address that getaddrinfo() told it to try to bind to, fail, and emit a bleat like the above.

[GENERAL] feeding big script to psql
Hi, A generated a big SQL script (about 20 Mb), and fed it to psql. I was very surprised that within a minute psql became quite slow. There were areas, where less than 10 row were inserted in a second. This is on a WinXP machine with local server 8.0.3, and only I use it. Looking at the log files of PG the commands are executed fast. I have monitored psql with te TaskManager, and it was at 45-50% CPU (this is Hyperthreaded, so 50% is the max for one thread), and the memory allocation/deallocation was very active, even about +-2Mb/sec. The command were simple create table and insert commands chunked into several lines like this: CREATE TABLE aeloleg( vevo CHAR(6), szallito INTEGER, datum DATE, hatarido DATE, vevo_nev CHAR(30), ir_szam INTEGER, helyseg CHAR(20), cim CHAR(20), befizetes INTEGER, terheles INTEGER, hitel INTEGER, rendeles INTEGER, jel CHAR(1), trans INTEGER, szoveg TEXT, storno BOOLEAN) WITHOUT OIDS; The insert commands for one table were surrounded by BEGIN and COMMIT like this: CREATE BEGIN INSERT INSERT ... INSERT COMMIT I know it would be faster with COPY, but this is extremly slow, and the bottleneck is psql. What is the problem?

I'm not worried about upgrading the database, that part will be easy as you indicated. My problem has nothing to do with upgrading the server side, it's upgrading my applications. The problem goes something like this: I installed PostgreSQL back in 1999 for a senior project I was doing in college. It came in Linux Mandrake 6.5. I wrote some wrapper modules that wrapped the Pg.pm functions with my own functions. Everything was good, and I liked the database engine. I upgraded to Mandrake 7.1 and the respective PostgreSQL database engine. Pg.pm was still there, so my apps still worked just fine. Everything was still good. I upgraded to Mandrake 8.1 and the respective PostgreSQL database engine (7.1.2-19mdk). Pg.pm was still there, and now I decided that I wanted to write some C++ applications that used PostgreSQL also, so I researched how to use libpq++.so. Everything was good. I even got a job implementing my software and writing more. From there, Mandrake 9.1 had a flaw with script execution, so I couldn't upgrade to it. Now I have to upgrade to Fedora Core 4, which uses a much higher version of PostgreSQL. Unfortunately the Pg.pm support is gone (it's wrapped by DBI/DBD, which wasn't that hard to convert my apps, and they work except for some inconsistent errors that I'll figure out later), and libpq++.so is gone (which is where the hard part seems to be coming in). So I have a choice... I can either rewrite my interface for the new proprietary objects for PostgreSQL or I can convert my apps to use the ODBC driver and not have to worry as much on future upgrades. The problem is that I got bitten in the behind by my choice to avoid ODBC and use the proprietary PostgreSQL drivers. It's unfortunate that they dropped the support, but it's their choice. The bad part is that it's the sole thing that's been keeping me from upgrading. -- Thanks, Laura Vance Systems Engineer ---(end of broadcast)--- TIP 4: Have you searched our list archives? http://archives.postgresql.org

Okay...lets dig into... template1=# select oid from pg_tablespace where spcname = 'disk1'; oid --- 594611987 (1 row) template1=# select * from pg_tablespace_databases(594611987); pg_tablespace_databases - 595675173 (1 row) Aha...so there seems to be a database associated to this tablespace - lets see which one - template1=# select * from pg_database where oid = 595675173; datname | datdba | encoding | datistemplate | datallowconn | datlastsysoid | datvacuumxid | datfrozenxid | dattablespace | datconfig | datacl -++--+---+--+---+--+--+---+---+ (0 rows) Mhh. Nothing. How may I delete the tablespace manually? Best regards Oliver ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings

Usually only a few installations need a cluster solution anyway. Did you try with optimized queries and a single machine postgres? You have online backup too so you dont need a cluster for this functionality. If it turns out you have to distribute load somehow, there is slony and pgpool.

I would never switch from pgsql to mysql. Here's a short list of the reasons why: http://sql-info.de/mysql/gotchas.html If they're having problems and haven't asked for help in these lists, then I'm willing to be they're just looking for an excuse to change to what they're comfortable with, and not really serious about using postgresql. Also, why pgcluster? why not slony or mammoth replicator? Both of those are fine pieces of software that handle most replication needs. Combine slony with pgpool and a few scripts and you've got quite a nice cluster setup. Of course, setting mysql up is a bit easier. But I don't trust their replication, and searching google for mysql and clustering and problems or what not will tell you why. Computer Science ain't easy, and picking a product because it seems easier to use up front is often the worst of all decisions. ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings

For pgcluster help, your best bet is to hit either their mailling list or their forums. http://pgfoundry.org/projects/pgcluster/ has more info.

The description for t_annotation shows the two references to t_node but no indexes on the referencing columns (ann_startnode_id and ann_endnode_id). When you delete records from t_node, the database has to check whether those deletions would cause a foreign key violation, so it has to search t_annotation for matching foreign keys. Without indexes on the referencing columns, the planner has to use a sequential scan instead of considering an index scan, so those searches are likely to be slow. Try creating indexes on the referencing columns (ann_startnode_id and ann_endnode_id) and on any other columns that refer to other tables. -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---(end of broadcast)--- TIP 6: explain analyze is your friend

Or should I try to build the query in a function and send it through dblink instead of dblink_current_query()? I've also been told that oracle has an auditing service that records every action the users make, including the queries issued. If pg has something like that I could use it instead.
