I don't know what is wrong with this. shridhar@bheem ~$ cat ~/.pg_service.conf [test1] host=localhost dbname=test shridhar@bheem ~$ strace -o psql.strace psql test1 psql: FATAL: database "test1" does not exist shridhar@bheem ~$ grep -i pg_service psql.strace shridhar@bheem ~$ psql test psql (9.2.2) Type "help" for help. test=# \q shridhar@bheem ~$ psql --version psql (PostgreSQL) 9.2.2 -- Regards Shridhar --------------------------------------------------------------------------------------------- The services file looked/looks interesting, but there are far too many clients, and at multiple sites, to manage this. I really need something on the server side, a single place to manage this for all connections regardless of where they are coming from. It also looks like a C lib based file, something I won't have access to except, maybe, through an app designed for DBAs to edit this file. If I am mistaken, and the services file is in the DB root area (the area specified after the "-D" in commands like pg_ctl), then maybe this is still viable. But I don't see a services file there :-(
