From: Jan Wieck <jwieck@debis.com>

here  is  the  patch  that  includes  PL/pgSQL into the build
    (currently with make errors ignored) and  adds  a  regression
    test for it. A clean build and regression ran fine here.

    Can you please apply it?

    The  tar  should  be  extracted  in  /usr/local/src/pgsql and
    creates the following files:

    src/pl/Makefile
            called by toplevel GNUmakefile and for now only calls
            src/pl/plpgsql/Makefile

    src/pl/plpgsql/Makefile
            calls  src/pl/plpgsql/src/Makefile  (here the call to
            make ignores build errors  -  this  must  be  changed
            later for the final release).

    src/test/regress/input/install_plpgsql.source
            SQL script installing PL/pgSQL language in regression
            database. Will be modified by  .../input/Makefile  to
            point  to  correct  PGLIB  directory where plpgsql.so
            gets installed.

    src/test/regress/output/install_plpgsql.source
            expected output for installation script.

    src/test/regress/sql/plpgsql.sql
            the main regression  test.  It  tests  functions  and
            triggers written in PL/pgSQL including views that use
            supportfunctions in this language.

    src/test/regress/expected/plpgsql.out
            the expected output for the above regression test.

    make_plpgsql.diff
            patch that adds some lines to
