That's pretty ugly :-(. I concur with Michael that there's value in
exposing the version number in the numeric form used by PG_VERSION_NUM.
However, I also concur with Andrew that if the use-case for this is
Makefiles, pg_config is a pretty poor transmission mechanism.
We should instead add PG_VERSION_NUM to the version variables set in
Makefile.global.
