urgent, Table not shown but files are there.

Hi All,

I have inherited a Postgresql DB server, this morning one of the tables is no
longer available to scripts and does not show up in psql.

The main directory for the database is still there and all of the files in it
including the file(s) for the table that is not showing up.

From what someone here said this has happened before and the old db admin
would just fix it in a couple of minutes, I'm new to Postgresql and have not a
clue.

Anyone seen this behaviour before?  Any ideas?


Thanks

How do you know the file is for that table? When you do a select * from
pg_class where relname = 'yourtable' what do you get?

This seems pretty bizarre to me, like your either telling us
mis-information or you've got serious hardware issues. I would guess you
could try to do a create table <yourtable> then look up the relfilenode
and copy your other table file over that one, but that might cause more
problems if I'm mis-diagnosing your description of the problem, so try
it on a backup server first if you can.

I'd recommend posting platform/version info as well before you go to
much further.
