I started work on proposed check statement option and there are a few questions?
what is sense of this statement for others PL? When we solve a mainly
PL/pgSQL issue, has sense to implement new statement? Isn't a some
problem in our CREATE FUNCTION design? A separation to two steps
should has a little bit strange behave - we cannot to check a function
before their registration (we can, but we should to do a some game
with names) - there is necessary some a conditional CREATE FUNCTION
statement - some like "CREATE CHECKED FUNCTION " or CHECK FUNCTION
with function body.
