Обсуждение: current database?

hi,
 when i do \c - postgres tells me which
database i'm currently connected to.  where
does it get this info?  i'd like to use it
in a program.

TIA,
  mikeo

It remembers this information from when you first connected, e.g., `psql
-d template1'.

If you're working directly with libpq, then PQdb() et al return
the connection parameters used to create the current PGconn object.
