Re: V8.3 fails to start after unremming hba_file = 'ConfigDir/pg_hba.conf'

Re-REM (called commenting for us non-windows geeks :-) the line
 
Look in your data directory, the file exists and is used automatically, you don't need to point the postgresql.conf file to it explicitly.

Look at:

  For details on configuring the file.

Good Luck
