Tom Lane 87f2ad1326 Fix plpgsql to release SPI plans when a function or DO block is freed. 
This fixes the gripe I made a few months ago about DO blocks getting
slower with repeated use.  At least, it fixes it for the case where
the DO block isn't aborted by an error.  We could try running
plpgsql_free_function_memory() even during error exit, but that seems
a bit scary since it makes a lot of presumptions about the data
structures being in good shape.  It's probably reasonable to assume
that repeated failures of DO blocks isn't a performance-critical case.

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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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/.
