Do you intend the following domain transition?
  user_t + user_sepgsql_proc_exec_t -> user_sepgsql_proc_t

Is there any reason why users should not invoke their functions
without domain transition?

The purpose of $1_sepgsql_proc_t is to avoid unconfined domain
to invoke user defined function (may be malicious one) without
checking its safeness.
