I'm trying to use MS Access with PostgreSQL and so want to configure an ODBC file for this. Testing it resulted in a connection timeout, so I looked at this to troubleshoot:
Adding a "tcpip=true" line to postgresql.conf and a line to permit a connection from the computer running Access to pg_hba.conf and then restarting PostgreSQL seemed to go without errors, but when I tried to run the psql command afterward, I got this error:
psql: error: connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused
Is the server running on that host and accepting TCP/IP connections?
The psql command worked again after I undid these changes, so I'm trying to figure out how they caused this error. The line I added to pg_hba.conf was as follows.
