Tom Lane 54bb91c30e Further tweaking of pg_dump's handling of default_toast_compression.
As committed in bbe0a81db, pg_dump from a pre-v14 server effectively
acts as though you'd said --no-toast-compression.  I think the right
thing is for it to act as though default_toast_compression is set to
"pglz", instead, so that the tables' toast compression behavior is
preserved.  You can always get the other behavior, if you want that,
by giving the switch.

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
