[GENERAL] Looking for a good ERD Tool
I'm looking for a good ERD tool that's designed to work with PostgreSQL... currently I use the one found here http://www.fabforce.net/dbdesigner4/index.php for MySQL, and I just create the actual tables and such by hand... kinda of a kludge, and I lose all the reverse engineering benefits... but cest'le'vie. Anyway, would like to find a similar tool specifically designed for PostgreSQL... does one exist or is it a futile search? ---(end of broadcast)--- TIP 8: explain analyze is your friend

That was the main reason for rejecting such proposals a few releases ago. It's possible that our subsequent cleanups in the coercion mechanisms would make this a feasible idea now. But I haven't investigated closely, and I don't believe anyone else has either. The short answer is definitely that it would take more work than anyone has so far cared to commit. regards, tom lane ---(end of broadcast)--- TIP 8: explain analyze is your friend

The next thing to check is whether the OID mentioned in pg_trigger (which I forgot already) is the same as the OID shown in pg_class, ie select oid from pg_class where relname = 'pl02_status_table'.

Well, PostgreSQL doesn't have "unsigned" types, unless you create your own. If you want to have unsigned type, you can add a check constraint or, even better, create a domain: CREATE DOMAIN usmallint AS smallint CHECK (VALUE >= 0); ...while this gives you unsinged smallint type, its probably not what you wanted. If you wanted a type which takes two bytes of storage and stores values from 0 to 65535 then, well... its not it. If you ask here, you'll probably get a good explanation why there aren't unsinged types. My guess is that unsigned types add complexity which is not really judged by their usefullness, but thats only a guess. If you need unsigned-like type for data consistency reasons, just CREATE DOMAIN as shown above.

I'm not sure. As far as I can tell nothing has happened to the
pl02_status_table, nor should anything have happened to it recently.
Its just a lookup table relating status ID's to descriptive names, and
it only has about 8 records in it, and the last change was several
months ago. I've attached the \d output of both tables, and everything
appears kosher to me. Is there something in particular I should look
for?

[GENERAL] Transaction id wraparound questions
It seems that we have not been vacuuming our production database properly. We have been explicitly vacuuming all tables individually but have not vacuumed the entire database. A recent vacuum of the entire database gave us the dreaded "You may have already suffered transaction-wraparound data loss." warning. We have so far encountered no problems but I am wondering about the safest course of action right now. We cannot easily take an outage to perform a full dump and restore. Questions: 1) What is likely to happen if we encounter transaction id wraparound? 2) Will a full database vacuum fix the problem? 3) Can it make things worse? 4) Other than dump and restore, what options do we have? Information: This query: select datname, datvacuumxid, datfrozenxid from pg_database; returns this: "Production",1173213507,2246955329 "template1", 938856359, 938856359 "template0",427, 427 All responses welcomed. __ Marc Munro signature.asc Description: This is a digitally signed message part

[GENERAL] 7.3.2 closing connections, sometimes
I hate to post as vague a description as this, but I don't think the devil is in the details this time. I may be wrong ... This project is running 7.3.2 on a RedHat 9 system. We plan to upgrade in a few weeks to Fedora Core and Postgres 8, so maybe this problem is not worth wasting too much time on, right now. This is a SOAP server, Apache with mod_perl, connecting to Postgres via DBI/DBD::Pg. Sometimes it gets in a mood, for want of a better term, where a specific SQL statement fails with the good ole message "server closed the connection unexpectedly". It will fail like this for several hours, then suddenly start working again. The SQL that it fails on works perfectly in psql; it always returns the exact data expected. It's a small table of perhaps a dozen lines, and does not change very often. I would suspect hardware except that a new machine behaves just the same. One of the puzzles is that nothing shows up in the log. The log is configured thusly: server_min_messages = notice client_min_messages = notice log_min_error_statement = error And yet only the only messages that show up are start and stop. I changed log_min_error_statement to notice like the others, and it hasn't failed since, but I doubt this is the cause, because it has gone thru these mood swings before without having changed the log level. It's not the soap server disconnecting from the SOAP client, because the server continues to log things. Did 7.3.2 have any problems that might cause random disconnects, or diconnects for some obscure but documented reason? Google found some, but none of them apply here, as far as I can tell. Or are there useful changes to logging that might track this down? Strace generated about 50MB of log file, too much for me! -- ... _._. ._ ._. . _._. ._. ___ .__ ._. . .__. ._ .. ._.

Re: [GENERAL] PostgreSQL sequence within function
I figured it out... the problem was calling nextval("seq") with double quotes.
Normally, you would do "select nextval('seq')". From within a function, calling nextval with single quotes around the argument, causes a syntax error.
SOLUTION:
you need to use "backslash escape" sequences around the sequence argument... example below---
CREATE FUNCTION sp_slide_create(int4) RETURNS int4 AS'DECLAREaScriptID ALIAS FOR $1;seqID int4 := nextval(\'genseq\'); -- the magic is hereBEGIN
INSERT INTO tblslides (slideid) VALUES (seqID);RETURN seqID;END;'LANGUAGE 'plpgsql' VOLATILE;

Data corruption (of the index, caused by a previous crash) 3. Programming error. It's probably worth running one of the "memtest" tools to check you don't have a fault with your RAM chips. It could also be a fault in your disk controller/drives, but that's harder to test for (unless you're seeing disk errors).

Re-index (see REINDEX command in manuals) the index in question, that can't hurt either if you've had a power-failure or similar in the past.
