description: Now that Domains have entered the domain (pun intended) of
PSQL, would it be possible to do things like:

create procedure myproc1 (i int check (value between 1 and 10), .. )
...
declare variable v_bool char(1) check (value in ('T', 'F') or value is
NULL);

I think this would enhance the current PSQL even more and allows for
better checking of values inside procedural code.

The ability to put constraints on input (and output) parameters and variables
could improve the code people write. I think it would be a nice feature.

Perhaps in Firebird 2.5 in combination with SQL based Stored Functions? ;)
