Subject: [PATCH] FindPostgreSQL.cmake: Add PATH_SUFFIX for searching.
This slightly changes lookup order: Namely, the system-folder "/usr/include/postgresql"
is now preferred over "/usr/include/" even if both container libpq-fe.h.
This finds the correct path on a standard Gentoo installation, where "/usr/include/postgresql"
is a symlink to the folder with all include-files for the user-selected postgresql-version,
while "/usr/include/libpq-fe.h" is a single symlink provided for backwards-compatibility.
Since ROOT uses also e.g. "pg_config.h", selecting "/usr/include/" over "/usr/include/postgresql"
leads to failure on Gentoo.
