No, of course it wouldn't --- the column coming out of the backend is
PG's "time" type either way.  I'm sure that the unwanted conversion to
a date or datetime value (with, evidently, implicit fill-in of today's
date) is happening on the client side.

I don't know if our ODBC code should be blamed or if it's a
client-application bug.  A quick look at the ODBC sources makes it
appear that the ODBC code reports ODBC type code "SQL_TIME" for a
PG "time" column, which seems a reasonable mapping to me, but I'm
no ODBC expert.

Hmm, so perhaps the problem could have been triggered by a recent "fix".
I looked at 7.1 and 7.2 ODBC sources and they seemed about the same in
this respect.  Do you know what version the GB driver was, exactly?
