Tom Lane 6f7c0ea32f Improve memory management for PL/Perl functions. 
Unlike PL/Tcl, PL/Perl at least made an attempt to clean up after itself
when a function gets redefined.  But it was still using TopMemoryContext
for the fn_mcxt of argument/result I/O functions, resulting in the
potential for memory leaks depending on what those functions did, and the
retail alloc/free logic was pretty bulky as well.  Fix things to use a
per-function memory context like the other PLs now do.  Tweak a couple of
places where things were being done in a not-very-safe order (on the
principle that a memory leak is better than leaving global state
inconsistent after an error).  Also make some minor cosmetic adjustments,
mostly in field names, to make the code look similar to the way PL/Tcl does
now wherever it's essentially the same logic.

Michael Paquier and Tom Lane

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
