Benoit,
Postgres doesn't fold all table and column names to lowercase. If the
identifier is enclosed in quotes then the case is preserved. Thus it is
possible to have three tables all named test but differing in their case:
TEST
Test
test
can all exist at the same time. However to reference TEST or Test the
identifier would need to be quoted (i.e. select * from "TEST"). All
unquoted references are folded to lowercase.
I haven't seen anything in the jdbc spec on how this should be handled.
Does anyone know what the spec says should be done in this area, or
what other databases jdbc drivers do?
thanks,
--Barry
