Failed to connect to database. Procedural languages files are installed, but are not activated in any database.

Failed to connect to database. Procedural languages files are
installed,but are not activated in any database.

Noted error appears on

windows XP, Serice Pack 1

with

postgresql 8.0 beta 1

using the installer.

After that, connection attempts via psql end with

psql: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

Looking at Service Control Panel, Postgresql is running , within the
data directory a PID-File is sitting quietly.

The owner of all files within data/ and subdirectories is "postgres"

also pg_admin fails with the same error.

I was running 7.x pre beta on WIN32 before on the same computer.

What can I change to make it work or to help diagnose the problem any further?
