Peter Eisentraut 46211da1b8 Use HTABs instead of Python dictionary objects to cache procedures 
Two separate hash tables are used for regular procedures and for
trigger procedures, since the way trigger procedures work is quite
different from normal stored procedures.  Change the signatures of
PLy_procedure_{get,create} to accept the function OID and a Boolean
flag indicating whether it's a trigger.  This should make implementing
a PL/Python validator easier.

Using HTABs instead of Python dictionaries makes error recovery
easier, and allows for procedures to be cached based on their OIDs,
not their names.  It also allows getting rid of the PyCObject field
that used to hold a pointer to PLyProcedure, since PyCObjects are
deprecated in Python 2.7 and replaced by Capsules in Python 3.

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/.
