Hi,
I have a large table with a timestamp field.
select cf03dthr from cf03t where cf03dthr <= '2003-12-31'::timestamp ORDER
BY cf03dthr DESC LIMIT 3
cf03dthr
---------------------
2003-05-27 01:01:01
2003-05-26 09:50:55
2003-05-26 09:49:54
(3 rows)
(...) where cf03dthr <= '2003-05-27' (...)
cf03dthr
---------------------
2003-05-26 09:52:28
2003-05-26 09:50:55
2003-05-26 09:49:54
(3 rows)
* But if I do: (...) where cf03dthr <= '2003-05-26' (...)
* I get: "ERROR: convert_timevalue_to_scalar: unsupported type 16976"
* This occurs in any other dates...
If I do: (...) where cf03dthr <= '2003-05-26 09:00:00' (...), for example,
the rows returns OK, but <= '2003-05-26 06:00:00' or many other
combinations give me the same error.
Thank´s for any help.

I could not reproduce this here. If your column is actually of a domain
over timestamp, then you may need some post-7.3.2 bug fixes; see the
just-released 7.3.3. Otherwise, please provide a self-contained test
case.

Tom,
Really the field is a Domain (datetime = timestamp without timezone).
And for information, this is a log table. If the criteria is more
"distant" of the most recent registers (50 or 60), the error occurs.
Thank´s Tom.....I will report my tests.

Ah. Okay, then the reason I don't see it is I have this 7.3.3 patch:
2003-03-22 20:49 tgl
* src/backend/: optimizer/path/indxpath.c, utils/adt/selfuncs.c
(REL7_3_STABLE): Tweak selectivity and related routines to cope
with domains. Per report from Andreas Pflug.
