Clarification:

I've modified configure[.in] so that a failed check for a PostgreSQL
header or library has the same effect as using --enable-postgres=no,
i.e. USE_POSTGRES is set to empty.

I haven't modified anything else, so USE_POSTGRES itself is still
being completely ignored.

Also, if the idea was to conditionalise PostgreSQL support in various
programs (rather than controlling whether or not to build
src.garden/grass.postgresql), USE_POSTGRES should probably be an
AC_DEFINE (which affects config.h) instead of (or as well as) an
AC_SUBST (which affects Makefile and src/CMD/head/head).
