(a) Why are you passing timestamps as text? Try to use 'timestamp' instead
of 'text' and then cast the values using ::timestamp (e.g. '2010-04-12
11:00:00'::timestamp).
(b) If you really need to pass the values as text, you can cast using
::text (so '2010-04-12 11:00:00'::text will do the trick).
(c) As the function returns boolean, you should use
select makesimplereservation(....) AS 'result';
and not 'select * from ...' - this should be used with SRF (set returning
functions) and I'm not sure if it will work with scalar values.
