That would also be a nice feature to rely on in extensions install.sql
files when you have major version dependant code. Defining a function,
calling it then removing it is what to do now. This new syntax would
greatly simplify the support code.
DO $$ IF postgresql_major_version = '8.2' THEN ...
ELSE ...
END IF;
$$;
(of course in this snippet example the ELSE covers it because the
CREATE EXTENSION stuff declared e.g. dependancy on postgresql >= 8.2).
