Tomas Vondra e9960732a9 Introduce a generic pg_dump compression API 
Switch pg_dump to use the Compression API, implemented by bf9aa490db.

The CompressFileHandle replaces the cfp* family of functions with a
struct of callbacks for accessing (compressed) files. This allows adding
new compression methods simply by introducing a new struct instance with
appropriate implementation of the callbacks.

Archives compressed using custom compression methods store an identifier
of the compression algorithm in their header instead of the compression
level. The header version is bumped.

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/.
