* [PATCH v2] Document wal_compression=on

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>
  0 siblings, 0 replies; 657+ messages in thread

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still

documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still

This was not included when lz4 support was added in

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

This was not included when lz4 support was added in

This was not included when lz4 support was added in

This was not included when lz4 support was added in

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>
  0 siblings, 0 replies; 657+ messages in thread

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

documented.

documented.

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still

documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

documented.

documented.

documented.

documented.

* [PATCH v2] Document wal_compression=on
@ 2026-06-29 09:58  Christoph Berg <myon@debian.org>
  0 siblings, 0 replies; 657+ messages in thread

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

This was not included when lz4 support was added in

documented.

* [PATCH v2] Document wal_compression=on

From: Christoph Berg @ 2026-06-29 09:58 UTC (permalink / raw)

This was not included when lz4 support was added in
4035cd5d4eee4dae797bfc77ab07f8dcd8781b41, but since the value is still
legal and even mentioned in postgresql.conf.sample, it should be
documented.

Update postgresql.conf.sample to say "on" is the same as pglz.

+1 for documenting this.

+        The value <literal>on</literal> is a deprecated alias for
<literal>pglz</literal>.

"deprecated" implies we may remove it someday. I don't think we'd gain
from doing that, but we could instead call 'on' a "historical
spelling" of 'pglz'.

Or perhaps leave the door open for picking a better default in the future?

     The value <literal>on</literal> is currently an alias for <literal>pglz</literal>.

(I would be fine with either of the 3 variants.)

Maybe we should also update the postgresql.conf.sample:

 #wal_compression = off                  # enables compression of full-page writes;
-                                        # off, pglz, lz4, zstd, or on
+                                        # off, pglz (or on), lz4, or zstd

(Or just delete it there.)

FYI, default value of wal_compression is "off".

Still, there is value in being consistent. If default_toast_compression=lz4
and I turn wal_compression "on", I would also accept lz4 there.

We are picking the best toast compression algorithm by default, we
should also do that for wal.

The thread subject is about documenting the state of affairs that have
existed since PG15. If you want to propose a change in behavior for
master, that's material for a separate thread.

I'm attaching v2 that implements this (without the "currently").

I pushed this with the change of using the language "historical
spelling" as mentioned upthread.
