Tom Lane be85727a3d Use PREPARE/EXECUTE for repetitive per-object queries in pg_dump. 
For objects such as functions, pg_dump issues the same secondary
data-collection query against each object to be dumped.  This can't
readily be refactored to avoid the repetitive queries, but we can
PREPARE these queries to reduce planning costs.

This patch applies the idea to functions, aggregates, operators, and
data types.  While it could be carried further, the remaining sorts of
objects aren't likely to appear in typical databases enough times to
be worth worrying over.  Moreover, doing the PREPARE is likely to be a
net loss if there aren't at least some dozens of objects to apply the
prepared query to.

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:

	https://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
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
