I have been using PT3 on my Mac and have the postgres database all set up for that. I am now trying to run the trial of PT4, and when the Configure PostgreSQL Server window comes up and I click Connect it says

"Unable to connect to this database. Please check the configuration."

Please advise!

Can you connect to PostgreSQL through PGAdmin? Double check your password options - that error can occur if you're using a different password and the passwords don't match.

Sorry, I don't know what PGAdmin is. I'm not very familiar with how the whole PostgreSQL works to be honest.

Ok, I have updated PostgreSQL to version 9.0, found PGAdmin and attempted to connect to the server. I have tried all possible passwords including the default 'dbpass' which I don't imagine I would have changed, and the message is always "Server doesn't listen.....Is the server running on host "localhost" and accepting TCP/IP connections on port 5432?"

If it is a problem of the username/password, is it possible to reset this? Or delete the whole thing and reinstall from fresh? I have tried looking for the uninstaller in the PostgreSQL 9.0 folder but there was none.

Let's check first to see if the server is running. Open Applications -> Utilities -> Terminal and at the terminal type:
ps auxw | grep -i postgres

and post the output here for me please.

Hi,

I am facing the same issue - cannot connect to database.

This is what I get after keying in 'ps auxw | grep -i postgres'

Unfortunately Kraada isn't around this weekend and I'm not sure what this output means exactly.

That doesn't look as if any PostgreSQL processes are actually running.
Please read this guide which walks you through the PostgreSQL installation, and how to fully uninstall first which is necessary if you have a partial installation which isn't working.

Again Kraada may be able to tell more from your output when he returns, but without more information I'm not sure what to suggest. How did you install PostgreSQL on this machine? Depending on your situation you may want to follow the same guide as above.

It looks like you've been running some normal applications as the postgres user - did you log in as that user and try to do things that way? That should not be necessary - PostgreSQL runs as that user in the background.

Yea the previous PostgreSQL installation required me to change my username to postgres and did not create it as a separate user.

Anyway, managed to solve the problem as advised by WhiteRider - deleted the database and reinstalled postgres, now works a treat. Thanks
