This adds a new object type "procedure" that is similar to a function but does not have a return type and is invoked by the new CALL statement instead of SELECT or similar. This implementation is aligned with the SQL standard and compatible with or similar to other SQL implementations. This commit adds new commands CALL, CREATE/ALTER/DROP PROCEDURE, as well as ALTER/DROP ROUTINE that can refer to either a function or a procedure (or an aggregate function, as an extension to SQL). There is also support for procedures in various utility commands such as COMMENT and GRANT, as well as support in pg_dump and psql. Support for defining procedures is available in all the languages supplied by the core distribution. While this commit is mainly syntax sugar around existing functionality, future features will rely on having procedures as a separate object type.

src/pl/plperl/README PL/Perl allows you to write PostgreSQL functions and procedures in Perl. To include PL/Perl in the build use './configure --with-perl'. To build from this directory use 'make all; make install'. libperl must have been built as a shared library, which is usually not the case in standard installations. Consult the PostgreSQL User's Guide and the INSTALL file in the top-level directory of the source distribution for more information.
