The only thing that we have been able to point to on the box in question is a hardware problem. In view of the disk being RAIDed, the causes seem to fall to three things being most likely sorts of culprits: 1. Perhaps the controller is glitched; 2. Perhaps the controller driver is glitched; 3. Perhaps there is a RAM problem. Notice that the list of suspects doesn't include any that actually relate to database software. Your best bet is to look for hardware problems. We ran a full RAM test for 15 hours... it came up with NO problems.

[GENERAL] Can I reset the lower bound of an array.
Hi, I've been playing about with array's, and found the concat operator '||' quite useful, apart from the fact that prepending an element places it in a lower subscript. Is there a way of either: a) prepending an element, but shifting existing elements up a subscript, so that the lower bound remains the same? eg: 1 || ARRAY[2,3,4] -- new operator || shift array and prepend or b) resetting the lower bound of the array (without affecting elements)? eg: set_array_lower(1 || ARRAY[2,3,4], 1) -- 2nd arg is the new lower bound Also, while on the topic of array's: Is there any way to specify array slices from a subscript to the beginning or end of an array? eg: element to end: array[5:*] beginning to element: array[*:5] At present it is possible by using an extreme +ve or -ve subscript value, but this isn't nice.

Re: [GENERAL] Anyone using pgreplicator?
Replying to my own post, tch, tch... :-) Thanks to those of you who have contacted me off list. It seems that there's a fair bit of interest in replication in general at the moment. I fixed my problem with pgReplicator, so the test system is merrily replicating between Perth and Brisbane as I type. Bandwidth usage is low at the moment. The problem was embarrassingly simple once I checked the actual SQL being received on the remote server. (Thanks Stef of .za for the suggestion). When pgReplicator creates its replication changes to a data base it adds its own unique ID. I did this independently when I initially set this up. This meant that the id for records that I considered to be identical were actually different according to pgreplicator and therefore updates couldn't find the corresponding record to update in the remote system. As I said, embarrassingly simple! The trick when setting up a replicated multi master db is to first of all create the combined db, create the pgr replication schema on this combined db, and then distribute this db around to all sites. Only then do you make the site specific changes (eg, to pgr_lsite, and any locally independent tables). Note that this is the opposite approach to that on the website. Alternatively, (I haven't tried this) one could distribute a schema only db, put the site specific data into it and let replication handle the filling of the common data, by dumping the data as user replicator, then loading it again as a real user. Hope this helps someone else avoid my mistake. Alan Graham On Thu, 2004-04-15 at 22:11, Alan Graham wrote: Apologies if this is off topic, but I've tried the pgreplicator forums, and they appear to be dormant.

Everything in fact works. Except that it doesn't actually replicate. When I synchronise. I can see the traffic going between the sites. I can see the record being replicated appearing on the flow table, I can see it on the history file on both the source and the destination, so it's reaching the destination. There is no sign of any error in any of the pgreplicator logs or the system logs. I've even started postgresql in debug log mode and tailed the log while started the replicator on the remote site. I see the communications come in, and see the commands being entered. But the data isn't being changed on the destination. Any pgreplicator users out there seen this sort of thing before? I thought it might be a permissions issue, but all users have full access. The replicator user can make the changes by submitting an SQL update. pgreplicator has a 'rejected sql' log file, but that's empty. I'm at my wits end...

[GENERAL] PostgreSQL on SMB/CIFS Shares on FreeBSD 5
I have an embedded system running FreeBSD (5.1) that does not have any local
(rotating) storage (i.e disk drives).
PostgreSQL also runs on this box and (at this point) has two tables. It is
an extremely simple PostgreSQL configuration with the tables having less
than 20 fields each, and no relations between the tables.
However, because there isn't any (substantial) local storage available on
the Compact Flash, and the tables have the potential to grow fairly large,
Windows-based shares are being used (via PostgreSQL's 'initlocation') as the
backing store for the tables.
Moreover, setting the system up consisted of:
1. Setting and exporting PGDATA2=/var/nsg/dbNSG in ~/.profile
2. mount_smbfs [EMAIL PROTECTED]/share /var/nsg/dbNSG
3. initdb (default location (/usr/local/pgsql/data) (on the flash))
4. start PostgreSQL
5. createuser -A -D nsg
6. initlocation -D PGDATA2
7. createdb -D PGDATA2 -O nsg nsg
8. (create tables)
This all completes successfully, the problems begin while attempting to
populate the tables. It seems that attempts to add specific records causes
my C/libpq application to forever block on 'postgres'. My app is blocked on
select(2) (via pg_exec('INSERT...')) and PostgreSQL is blocked on a
semaphore. And for the record, the application and PostgreSQL perform
flawlessly if step 2 (above) is skipped. In other words, there seems to be
problem when SMB/CIFS is layered in.
Does anyone have any information that might shed a little light? Anyone use
SMB/CIFS as the backing store for PostgreSQL?
Thanks in advance!

Re: [GENERAL] convert result to uppercase
How do i convert a result to upper/lowercase?
I'ld like to do the following:
SELECT UPPER(lang) from languages;
and get for example uk as UK, dk AS DK and so on?
That looks right to me. Are you getting an error?
lee=# select version();
version
-
PostgreSQL 7.4.2 on i386-portbld-freebsd4.9, compiled by GCC 2.95.4
(1 row)
lee=# select UPPER('MixED CaSes');
upper
-
MIXED CASES
(1 row)
lee=# select lower('MixED CaSes');
lower
-
mixed cases
(1 row)

Both the IP and the HELO checks would be quite useless if I used an MX that wouldn't support 'em. Yup. If you can't employ the same anti-UCE checks on a secondary as you can on a primary, dump the secondary. Secondary MX' are of no value if they just queue things up for the primary, anyway. Nowadays, yeah :-(. Still another part of the internet that spammers have managed to render nonfunctional --- backup MX service used to be essential, but now it's better to risk losing incoming mail than to accept a ton of spam that didn't get filtered properly.

[GENERAL] Slony-I heading for release
The Slony-I project is currently heading for release. The plan is to start BETA around May 12 with a target release date end of June. Nightly CVS exports can be downloaded from here: http://gborg.postgresql.org/project/slony1/projdisplay.php I would like to encourage everyone who intends to use Slony-i for and has not done so yet, to start testing the software immediately. As the PostgreSQL main project, Slony will follow the strict no new features in past releases rule to the letter. There is also a step-by-step example how to install and setup replication. For instant help, I am usually available on the IRC channel #slony on freenode.net. The largest problem left is that the project misses an autoconf and build environment expert. As a result of that, building and installing Slony-I currently requires the original build tree of the PostgreSQL installation to include the original Makefile.global and use other parts of the make process. If anyone out there feels fit to untangle this, you are highly welcome!

[GENERAL] TPC H data
Hello, We are trying to import the TPC-H data into postgresql using the COPY command and for the larger files we get an error due to insufficient memory space. We are using a linux system with Postgresql-7.3.4 Is it that Postgresql cannot handle such large files or is there some other possible reason.
