When trying to connect to psql to 'postgres' it gave me the (0x0000274D/10061)...
Now have I followed this guide: http://www.pokertracker.com/products/PT3/docs/PokerTracker3_Manual_Uninstall_Reinstall_PostgreSQL.pdf step by step, Except that I tried one second time to call my user something else than postgres.
During installation, during Activating Procedural Languages I got the error :
"Failed to connect to the database. Procedural languages files are installed, but are not activated in any databased. Could not connect to server: (0x0000274D/10061) Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?"
And during Activating contrib modules, error:
"Failed to connect to the 'template1' database.Contrib files are installed, but are not activated in any databased.Could not connect to server: (0x0000274D/10061) Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?"
Then PostgreSQL got "successfully" installed on my system.
