Being as I was sort of the person who got EXECUTE into plpgsql... I find
it odd that people think you can execute random shell commands.. AFAICS,
EXECUTE is used to execute SQL queries (for when you don't want to cache
the query plan?) ...
EXECUTE '' CREATE TABLE '' || NEW.dbs_name || '' ( '' || NEW.dbs_name || ''_id serial, '' || NEW.dbs_name ||
''_namevarchar(20), '' || NEW.dbs_name || ''_desc text, '' || NEW.dbs_name || ''_qty int4 );'';
I don't see how anybody could think you are allowed to execute random
garbage through exec*()...
