Michael Paquier 6b59bd710b Add tests for low-level PGLZ [de]compression routines 
The goal of this module is to provide an entry point for the coverage of
the low-level compression and decompression PGLZ routines.  The new test
is moved to a new parallel group, with all the existing
compression-related tests added to it.

This includes tests for the cases detected by fuzzing that emulate
corrupted compressed data, as fixed by 2b5ba2a0a1:
- Set control bit with read of a match tag, where no data follows.
- Set control bit with read of a match tag, where 1 byte follows.
- Set control bit with match tag where length nibble is 3 bytes
(extended case).

While on it, some tests are added for compress/decompress roundtrips,
and for check_complete=false/true.  Like 2b5ba2a0a1, backpatch to all
the stable branches.

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/.
