I was just looking at the git history and bumped into this thread. I
think Andrew got it right to revert 9e24109 with 6741cfa: these
routines should be declared and return dummy results for non-SSL
builds or applications are going to have a hard time maintaining
compatibility with libpq depending on what they link to if they get to
call those SSL new routines.
