Обсуждение: I can't access the database

I'm running an intranet service with php and postgresql 6.5.3 (I KNOW
THIS IS AN OLD RELEASE) and the pgsql stopped responding.

I have runned vacuumdb --verbose on my database and I get the following
message:

NOTICE:  --Relation master_en_curso--

When I run it a second time the message is like this.

pqReadData() -- backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally
        before or while processing the request.
We have lost the connection to the backend, so further processing is
impossible.  Terminating.
vacuumdb: database vacuum failed on diamnet.

I can't see the tables in the database or execute querys.
Anyone has a clue about this ?

You have corrupted data in that table.  If you can pg_dump, do so
and re-initdb (preferably after updating to some newer version...)
