How so? It'd be the same as far as I can see.
However, you could avoid any explicit use of pg_class by using the
regclass type instead:
OPEN cur_overlap FOR SELECT *, tableoid::regclass AS table FROM calendar_entries WHERE (start_date, end_date) OVERLAP
(new_start_date,new_end_date) AND property_id = X;
As far as the reason for the difference between function execution and
manual execution: check for unintended variable substitutions. Which
words in the query match variable names in the plpgsql function? Are
those only the ones you intended?
