Hi there,
Perl script pg_backupcluster calls psql and pg_dump with a --cluster
option:
pg_dump --cluster 14/test ...
However, this option is not documented (at least I didn't find anything)
and also I didn't find anything in the sources on GitHub.
It postgresql-common provided as part of the Debian/Ubuntu packaging. If
you want the documentation then:
man postgresql-common
Actually, I only have the 14/main instance and cannot really test
accessing the `test` cluster. However, psql and pg_dump actually work
with --cluster 14/main and report an error when I specify 14/test so,
the option --cluster seems to work. Is it intentionally not documented?
So, whats the recommended way to connect to a specific cluster? Is it
just the port?
On Debian/Ubuntu using their packaged versions then use the
postgresql-common tool, it makes things a lot easier. Otherwise follow
the instructions others have provided for using -h and -p. You will also
need to do -h/-p if you are trying to reach remote instances of Postgres.
