psql : Error: Cannot stat /pgdata/8.2/main

From

Hi,

I have moved my database files from their default location to their own
partition on with their own controller and disks. PostgreSQL works OK
and I can connect with Pgadmin (Debian Lenny AMD64, PostgreSQL 8.2.4).

When I want to connect with psql however (with a non-root account) I get
the following:

panoramix:~$ psql -d my_database
Error: Cannot stat /pgdata/8.2/main

/pgdata/8.2/main is the location where the database files are actually
located.

Why do I get this error and what should I do to be able to connect to
the database?

TIA

psql itself has no business touching the database directory, and a quick
search of the source code shows no instance of "Cannot stat" anywhere in
released PG sources.

I think you are being burnt by some misbehavior of Debian's wrapper
patches, and a complaint directed there is the next step for you.

It shows up a couple of times in the Debian wrapper scripts, when it's
trying to figure out which socket to actually connect to. It only gets
there after giving up on reading postgresql.conf and after giving up on
/var/run/postgresql. From the bug Joost filed in the Debian bts[1], it
looks like the Debian upgrade script got confused somehow.

Cheers,

Pasc
