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?
