Subject: PG 14 pg_basebackup accepts --compress=server-zst option
Date: Thu, 6 Jun 2024 21:54:20 -0400
Message-ID: <CANzqJaB=-AUnoXh+V6ayLPbRut7yNt7utL-=0+OK4hdh35-cTQ@mail.gmail.com> (raw)

https://www.postgresql.org/docs/14/app-pgbasebackup.html doesn't mention
"--compress=[{client|server}-]method".  That first appears in the v15 docs.

And yet pg_basebackup doesn't complain about an invalid option.
(Technically, this is a bug; I first noticed it a week after copying a
script from a PG 15 server to five PG 14 servers, and running it quite a
few times without fail.)

$ pg_basebackup \
>             --pgdata=$PGDATA \
>             --dbname=service=basebackup \
>             --verbose --progress \
>             --checkpoint=fast \
>             --write-recovery-conf \
>             --wal-method=stream \
>             --create-slot --slot=pgstandby1 \
>             --compress=server-zst ; echo $?
