Properly discover a connection is closed in postgresql_adapter
PQstatus doesn't properly test if future operations will succeed. A
PQping function is added to libpq in PostgreSQL 9.1, but if we rely
on it, everyone on earlier versions of Postgres is out of luck,
and the pg gem wouldn't have the 'fix' until the next release.
Thanks to @cbrecabarren and @ged for handling all the dirty details.
Closes #3392.
