That's a broken expectation. All that can realistically be expected
is database/catalog-level constraints.
Well, it isn't, and I don't think Postgres should encourage them to
think it is.
Adding such a feature would NOT be encouraging them to think this -
the documentation could be very explicit about this fact. Maybe
that's what Oracle is selling, and that's crappy of them, but that
doesn't mean we should use that as justification to not add a more
appropriate implementation.
As for the expectation above - could pl/pgsql be made compilable? It
would seem easy to translate pl/pgsql code into C and compile a C
function. That *could* go onto customer-controlled machines and be
safe from the customer's eyes.
FWIW, I think most people who want to hide code aren't concerned about
IP, they're concerned about clients seeing embarrassingly bad/sloppy
code. But there *are* some very real and legitimate needs for this,
though it's a small minority of those who think they do.
