Indeed. Use pg_backend_pid() instead:
SELECT whatever FROM pg_stat_activity WHERE procpid = pg_backend_pid();
A difficulty with this in existing releases is that pg_stat_activity
lags behind reality, so that you won't see your session listed in it
until you've been connected at least half a second or so. 8.2 won't
have that problem.
