Do I have that right?Correct. Postgresql has tablesspaces, but tools like pg_restore and PgBackRest are least confusing when all user databases live in the same $PGDATA/base. "CREATE DATABASE foo;" handles all that for you.If you really want your user databases spread all over, then one possibility is that each has its own instance (aka cluster) and port number.Ubuntu has pg_lsclusters to help manage that, but other OS's require something like "netstat -an | grep :543[2345]" (which doesn't help if an instance is shut down.On Fri, Aug 30, 2024 at 9:17 AM Scott Ribe <scott_ribe@xxxxxxxxxxxxxxxx> wrote:You should take a step back and read the basic documentation on PG administration. For instance: https://www.postgresql.org/docs/16/creating-cluster.html
We (at least I) have been assuming that you wanted to create a new database cluster, to run a server against that storage, using initdb. Using an already running server to put data elsewhere, using createdb is different, and requires that you create a tablespace first: https://www.postgresql.org/docs/16/manage-ag-tablespaces.html
