Thread: could not open relation "pg_trigger_tgrelid_tgname_index"

Hello to everybody.

I'm running PostgreSQL under Cygwin on Windows 2000 SP4.

I'm receiving the following error on ANY connection to our main database:
pgsql: FATAL: could not open relation "pg_trigger_tgrelid_tgname_index":
No such file or directory.

Connections to template1 succeed, template0 is not accepting any
connections and other test databases under the same PostgreSQL instance do
work.

I already tried restarting the service and it does well, but still doesn't
allows us connections to the main database.

I can't even connect to do a dump, so I can re-init the DB. The problem
started suddenly like 2 days ago.

Is this a known issue? I'd like to know if there is any available help and
if there is any other information useful to diagnose this problem.

Thanks in advance.

Octavio.

Hi, everybody!

I already solved it. Thank you.

First of, I forgot to mention the version(), so FYI, 7.4.1.

I followed Tom's advice in
http://archives.postgresql.org/pgsql-general/2004-03/msg01073.php

I shut down the PG instance.
postgres -D $PG_DATA -O -P $DBNAME
=# REINDEX DATABASE tbc_gamma
<EOF>

-P was necessary for the standalone backend to ignore the (damaged) indexes.

Done.

Hope this helps someone else someday.
