Tom Lane 1d2f9de38d Fix freshly-introduced PL/Python portability bug. 
It turns out that those PyErr_Clear() calls I removed from plpy_elog.c
in 7e3bb08038 et al were not quite as random as they appeared: they
mask a Python 2.3.x bug.  (Specifically, it turns out that PyType_Ready()
can fail if the error indicator is set on entry, and PLy_traceback's fetch
of frame.f_code may be the first operation in a session that requires the
"frame" type to be readied.  Ick.)  Put back the clear call, but in a more
centralized place closer to what it's protecting, and this time with a
comment warning what it's really for.

Per buildfarm member prairiedog.  Although prairiedog was only failing
on HEAD, it seems clearly possible for this to occur in older branches
as well, so back-patch to 9.2 the same as the previous patch.

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/.
