Обсуждение: drop table error

Hi all;

anyone know what would cause errors like this (postgres version 8.1.15):

drop table bigtab1;

ERROR: could not find tuple for constraint 373617

drop sequence bigtab2_id_seq;

ERROR: cache lookup failed for relation 371698

Thanks in advance...

Looks like system catalog corruption to me.  If you're lucky it's only
index corruption and you could fix it with "REINDEX SYSTEM <databasename>"

I seem to recall that you've had a LOT of stability problems in the
recent past.  I'm thinking that there is some underlying problem
with your system -- maybe bad hardware or a nasty kernel bug.
If Postgres were this unstable for everybody, nobody would use it.
