[ADMIN] Writing to a database or schema on a slave

[Wells Oliver]

Hey everyone. I'd like to create a schema on my slave so that users who do
not have access to the master can create some data. Clearly this data won't
be replicated, since it's on the slave, but will it cause any problems w/
data integrity to have it on the slave?

What are you using for replication?

Then the replica must be read-only; you can't create anything on
that PostgreSQL instance because it is a block-level copy of the
master database cluster. You would need to use logical replication
(for example, Slony) to do what you describe, or store the new
schema on another cluster and use dblink or a foreign data wrapper.
