Do not call initdb from Makefile's post-install. Users are required to
manually run initdb, maybe after configuring their preferred database
location in pgsql's user .profile. pkg_add used to simply replace some
existing data files.
Add pkg-message to tell the user about initdb.
Remove 2 empty directories from pkg-plist (pgsql/include/port/freebsd,
pgsql/include/port), since they are not included in "make package" anyway
and cause pkg_deinstall to complain about the plist.
Remove all pgsql/data contents from pkg-plist, so "make deinstall" and
pkg_delete won't clobber existing databases. Minor version upgrades can now be
performed by means of pkg_delete and "make install", without using pg_dump.
Chown %D/pgsql/lib to root:wheel to satisfy ldconfig's recent security
requirements.
Change @dirrm of pgsql to "@unexec rmdir": pkg_deinstall won't complain if
data still exists in that directory at deinstall time.
