Just to add, the connection string I try for pgbouncer is EXACTLY the
same as the one I use to connect directly to PG, but I add the port
number.

For Direct PG  (works) --
pg_connect("host=localhost dbname=$db user=myuser password=mypass");

For Pgbouncer  (does NOT work) --
pg_connect("host=localhost dbname=$db port=6432 user=myuser password=mypass");

Given that both PG and postgresql are alive and kicking on 5432 and
6432 ports respectively, as shown in the netstat output above, I
wonder if the connection string is the problem.
