Hi all !
Attached find some table and view definitions from the
GNUmed (www.gnumed.de) database.
Unfortunately I do not understand why PostgreSQL says
psql:xx.sql:14: ERROR: could not implement UNION
DETAIL: Some of the datatypes only support hashing, while others only support sorting.
when I say
select * from dem.v_message_inbox;
I mean, I (hope I) do understand what PostgreSQL tries to
tell me but I don't know how to find out which columns are
affected ...
Thanks !
Karsten
