Is the server running on host “127.0.0.1” and accepting TCP/IP connections on port 54

[AndreiaM55]

I have a problem when i try to access to postgresql:

: pg_pconnect() [function.pg-pconnect]: Unable to connect to PostgreSQL server: could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432? Can you help me please?

And i don't have permission to access to folder lib.

I've tried many solutions, but nothing works! I'm using ubuntu 12.

Can you help me, please?
