The issue is when you overwrite PIECES of an install, and their
inconsistent.  I want to
put it in libpq, since that is what makes the connection to the server. 

pg_config doesn't link to libpq at all.

The issue is what psql (and any libpq using program) is going to use to find
the UNIX socket. 

we have the unix_socket_directory GUC, but that doesn't show the
DEFAULT_PGSOCKET_DIR that libpq is using, 
and in fact there is no where that the server exposes it's default, either.
I'm wondering
if we should expose it's default in unix_socket_directory when the config
doesn't set it.
