Обсуждение: pgsql: Extend pg_config to be able to report the build-time values of

Log Message:
-----------
Extend pg_config to be able to report the build-time values of CC,
CPPFLAGS, CFLAGS, CFLAGS_SL, LDFLAGS, LDFLAGS_SL, and LIBS.  Change it
so that invoking pg_config with no arguments reports all available
information, rather than just giving an error message.  Per discussion.
