Description

Change implicit primary key column's type to UUID. Replace calls to gen_random_uuid with calls to rand_uuid,`gen_random_uuid` function should be removed.

As a part of this ticket update SQL grammar to make it possible to specify function calls (without arguments) in for DEFAULT column values. Because at the moment it looks like some functions that have no arguments can be called with omitted parentheses and that is not the case.
