Tom Lane 5ef26b8de3 Use LOAD not actual code execution to pull in plpython library. 
Commit 866566a690 is insufficient to prevent dump/reload failures
when using transform modules in a database with both plpython2 and
plpython3 installed.  The reason is that the transform extension scripts
use DO blocks as a mechanism to pull in the libpython library before
creating the transform function.  It's necessary to preload the library
because the dynamic loader won't do it for us on every platform, leading
to "unresolved symbol" failures when the transform library is loaded.
But it's *not* necessary to execute Python code, and doing so will
provoke a multiple-Pythons-are-loaded error even after the preceding
commit.

To fix, use LOAD instead of a DO block.  That requires superuser privilege,
but creation of a C function does anyway.  It also embeds knowledge of
the underlying library name for each PL language; but that's wired into
the initdb-time contents of pg_pltemplate too, so that doesn't seem like
a large problem either.  Note that CREATE TRANSFORM as such doesn't call
the language module at all.

Per a report from Paul Jones.  Back-patch to 9.5 where transform modules
were introduced.

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/.
