Unlike the relistemp field which it replaced, relpersistence must be set correctly quite early during the table creation process, as we rely on it quite early on for a number of purposes, including security checks. Normally, this is set based on whether the user enters CREATE TABLE, CREATE UNLOGGED TABLE, or CREATE TEMPORARY TABLE, but a relation may also be made implicitly temporary by creating it in pg_temp. This patch fixes the handling of that case, and also disables creation of unlogged tables in temporary tablespace (such table indeed skip WAL-logging, but we reject an explicit specification) and creation of relations in the temporary schemas of other sessions (which is not very sensible, and didn't work right anyway).
