revoke that again if he changes his mind ("drop language plpgsql" in
template1). initdb-time switches are not an adequate answer, not least
because most packagers don't make it easy to control them.
The way I intended to do it would indeed allow it to be undone simply by
executing 'drop language plpgsql' in template1.
I'm not clear about what else you want.
