maybe I'm missing something but it seems like it's behaving as expected. pgbouncer advertises a version that both seems to be understood by the protocol and is incompatible with any real postgres version. since such connection only allows plain SHOW statement, the warning about some psql features seems perfectly accurate, if not wildly an understatement as literally no psql feature will work. > >
