It is working well, but because it does static analyse only, sometimes it can produces false alarms or it should to stop a analyse, because there are not necessary data.
I see one possible solution in introduction of pragma statement with syntax:
PRAGMA keyword [content to semicolon];
The pragma has a relation to following statement. So the issue 36 can be solved by pragma
PRAGMA cmdtype CREATE;
EXECUTE format('CREATE TABLE xxx ...
The PRAGMA statement does nothing in runtime. It works only in compile time, and add a pair of key, value to next non pragma statement. This information can be used by some plpgsql extensions.
