tables?
You're more likely to run into problems with large fields being toasted
than plain large tables. IIRC Oracle's large object support is better
than PostgreSQL's.

The Oid will wraparound when it reaches the 32bits unsigned integer limit.
If you don't use the oid explicitely in your application, then you don't
worry about it.
Except IIRC the OP is running 7.4 which doesn't have checks in DDL code
to deal with OID collisions. :(

) CRC'd, because there was
extensive discussion around 32 bit vs 64 bit CRCs. There is no such
check for data pages, although PostgreSQL has other ways to detect
errors. But in a nutshell, if you care about your data, buy hardware you
can trust.

This is not good news! :(
What about other long runing 7.4.x DBs? Do you really have to dump
on the subject of oids

Basically, it's best if you just don't use them.

Anyway, how would be the chances for PostgreSQL to detect such a

BTW, 'row value' seems a bit prone to confusion (could be interpreted as
the row itself). It'd probably be better to say 'field'. Barring
objections, I'll submit a patch.

process will be the only
process that can see it. When you are through with it, delete the record, all
within the same transaction, and your purpose will be served.
If you use a temp table for that, you can have it truncate on
commit/rollback.

This tells me that you need to be vacuuming more. Autovac is your
friend.

Slony, pgmirror, and I think
this for a bunch of
tables is to write some code that will generate the trigger code for
you.
BTW, you can also do the auditing with rules. Just remember that you
can't reliably audit SELECTS, since someone could always do:
BEGIN;
SELECT ...
ROLLBACK;

, only a VACUUM FULL will.
If that drops the size of the relations substantially, you'll probably
want to REINDEX everything to reclaim lost space in the indexes as well.

disappointed with the performance of MyISAM and it's table-level

performance.

run vacuum inside of function.
Any thoughts?
Best bet would probably be to turn on autovacuum. Short of that, setup a
cronjob.
