Hi,
We're running pgsql 7.3.14 (yes I know it's old, an upgrade to 8.3 is planned).
Since a couple of weeks postgres loses the table definitions from apparently
random tables. A 'broken' table actually still works but a \d table gives
nothing. Currently The biggest problem is that these broken tables don't appear
in the backups.
example:
mydb=# select * from toegevoegde_dienst_omzetting_history limit 1;
omzetting_id | toegevoegde_dienst_id | datum_aanvraag | datum_ingang |
datum_uitgevoerd | product_soort_id_oud | product_soort_id_nieuw | id |
door_wie | sinds

(1 row)
mydb=# \d toegevoegde_dienst_omzetting_history
Did not find any relation named "toegevoegde_dienst_omzetting_history".
mydb=#
And this table is obviously from the pg_catalog.pg_class table as well.
Has anyone any idea what may cause this? I can't find anything in the logs
regarding the missing tables. (eg. that someone messes the pg_catalog tables).
I disabled the nightly vacuum process but the problem persists.
Could this problem be fixed by inserting the right records back in to in de
pg_catalog tables? is there a way to dump the pg_catalog tables?
The pgserver is running on a 4 CPU dell 6850 with 16G of Ram with Fedora Core 4
on a reiserfs filesystem without any problems for years. And nothing has
changed on the server side of things.
thanks,
alex.
