I am curious about receiving an error on updating/inserting into a temp table when a replication for "all tables' is created in PG 10.6. Given temp tables are not replicated, it seems odd that an update fails unless a replication identity is defined.
To reproduce, try the below code. Uncomment line 3 and the error is gone of course. It just seems like the identity should not be need to be defined on a temp table since it won't be replicated anyway.
CREATE publication test1 FOR ALL TABLES;
CREATE TEMP TABLE testing123 ON COMMIT DROP AS ( SELECT 1 AS value );
/* ALTER TABLE pg_temp.testing123 REPLICA IDENTITY FULL; */
