Subject: pgsql: Document wal_compression=on

Message-ID: <E1wekVa-000qkY-0r@gemulon.postgresql.org> (raw)
Document wal_compression=on
Commit 4035cd5d4 added LZ4 compression for full-page writes in WAL, and
retained "on" as a backward-compatible way to specify the builtin PGLZ
method. Document this meaning of "on" and update postgresql.conf.sample
to make the equivalence clear.
