Hi Raymond,
From a strictly relational viewpoint, this is as easy as

In english, that's the cartesian product of all users' uid and apps appcode

Looking at the create tablespace command in the docs, I was wondering
how easy it is to move a database/tablespace to another server/instance
of PostgreSQL.
We have lots of databases, with the same definitions, with 1 database
per client account on the server. I can setup the database
/ to the new
server? I assume the same PG version must be running on each server.
Will we have problems with the catalog tables? Would we still need to
dump/restore without data to copy over the catalog information and table
structures?

one that suggests you put your WAL files on a different physical drive from
