The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/16/runtime-config-wal.html Description:
In https://www.postgresql.org/docs/16/runtime-config-wal.html#GUC-WAL-COMPRESSION, the option "on" is not described: “The supported methods are pglz, lz4 (if PostgreSQL was compiled with --with-lz4) and zstd (if PostgreSQL was compiled with --with-zstd). The default value is off. ” "on" was an available option before PG 15, and still seen in some docs. If I understand the code in src/backend/utils/misc/guc_tables.c, "on" is the same as "pglz". So I suggest: “The supported methods are pglz, lz4 (if PostgreSQL was compiled with --with-lz4) and zstd (if PostgreSQL was compiled with --with-zstd). The default value is off. The value on is synonym of pglz.” I didn't see this discussed in https://www.postgresql.org/message-id/flat/3037310D-ECB7-4BF1-AF20-01C10BB33A33%40yandex-team.ru
