Yes. The backup is from production.
V9.4 is running on 5432 on all servers.
That particular restore happens to be on the dev server. 5433 is v12.

"C:\Program Files... is from the backup script. Production is always only

$pgdir is from the restore script.

or
PostgreSQL\15\bin

Turns out that it doesn’t work well to mix the exe from one and the port
from another.
