This commit moves the code in charge of deparsing the method and detail strings fed later to parse_compress_specification() to a common routine, where the backward-compatible case of only an integer being found (N = 0 => "none", N > 1 => gzip at level N) is handled. Note that this has a side-effect for pg_basebackup, as we now attempt to detect "server-" and "client-" before checking for the integer-only pre-14 grammar, where values like server-N and client-N (without the follow-up detail string) are now valid rather than failing because of an unsupported method name. Past grammars are still handled the same way, but these flavors are now authorized, and would now switch to consider N = 0 as no compression and N > 1 as gzip with the compression level used as N, with the caller still controlling if the compression method should be done server-side, client-side or is unspecified. The documentation of pg_basebackup is updated to reflect that. This benefits other code paths that would like to rely on the same logic as pg_basebackup and pg_receivewal with option values used for compression specifications, one area discussed lately being pg_dump.

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/.
