There are already acs-mail-lite-procs-oracle.xql and acs-mail-lite-procs-postgresql.xql and the query create_queue_entry for each.
So if you need to fix the oracle query, go ahead, the postgresql one works well.
However, I don't know if "db_dml create_queue_entry {} -clobs [list $body]" will work with postgresql, so it's what you need to check.
