Description:

I doubt this is a bug, but I cannot connect to remote systems running
Postgres 9.1 on Mac OSes.  I edited both the pg_hba and postgresql files
correctly but it continues to error out on two systems.  After making the
changes on my Windows box connections work fine.  Only seeing this on the
Macs
