Log Message:
Several changes to the postgresql80-* packages:

* Become maintainer for the postgresql80-* packages (ok'd by recht)

* Libtoolize postgresql80 build so that the shared libraries and
  loadable shared modules are built using libtool.  This should make
  PostgreSQL 8.0.x in pkgsrc build correctly on more pkgsrc-supported
  platforms.  This is accomplished with the Makefile.libtool file
  which replaces the Makefile.shlib file in the PostgreSQL distribution.

* Add libltdl modifications from the postgresql74-* packages so that
  this can work on Interix (untested).

* Fix some mismatches between static function declarations and their
  subsesquent definitions in the src/timezone module.  Fixes provided
  by Georg Schwarz.

* Convert PGSQL_USE_HIER into the PKG_OPTION "pgsql-hier-query", and
  teach both postgresql80-client and postgresql80-server to use it.

* Use BUILDLINK_TRANSFORM's "rm" action to remove unwanted compiler
  flags.

* Remove zlib/buildlink3.mk from postgresql80-client/buildlink3.mk
  as zlib is only used by the pg_dump client.

* Convert some files in files/* into patches that can be fed back
  to the PostgreSQL team.

* Install data and documentation files into share/postgresql instead
  of share/postgresql80 -- it's only possible to install one PostgreSQL
  version at a time in pkgsrc, and the new paths more closely match
  the rest of the installation paths.

* Add more mirrors to the MASTER_SITES list, and add a new variable
  POSTGRESQL_MIRRORS_SORT that has the same syntax as MASTER_SORT that
  can help people pick a nearby mirror.

* Nuke references to libpgtcl which is no longer distributed as part
  of a standard PostgreSQL installation as of version 8.0.

* Provide better documentation for Makefile.custom.

* Avoid linking in the pthread library in the correct way on NetBSD
  by setting DLOPEN_REQUIRE_PTHREADS=no.  Also, provide better
  documentation on why we can't enable thread-safety in the PostgreSQL
  libraries on NetBSD (at least for now).

* Preliminary support for installing postgresql80-* into a separate
  subdirectory under ${LOCALBASE} so possibly allow for multiple
  installations of PostgreSQL on the same machine.  Note that THIS
  DOES NOT WORK YET.

* Update the hierarchical-queries patch to "8.0.3-0.5.5" which fixes
  a bug which was crashing the backend when PRIOR was used in the
  target list.  The _level_ column is no longer automatically added
  to target list.  This makes it possible to use hierarchical queries
  as IN subqueries.  To get _level_ back you just have to explicitly
  mention it in target list.

Bump the following PKGREVISIONs:

	postgresql80-client	-> 2
	postgresql80-server	-> 2
	postgresql80		-> 1
