Hi all, One of the things I really like about PostgreSQL is that it normally does what I expect it to do - very little cognitive dissonance. But I'm puzzled by something I came across this evening - took me ages to figure it out! I have a table (sample) as follows (code on fiddle:): CREATE TABLE test (ts, te) AS VALUES ('2023-10-25 14:33:00'::TIMESTAMPTZ, '2023-10-25 15:56:00'::TIMESTAMPTZ); Now, this doesn't work: SELECT (ts, te)::TSTZRANGE FROM test; but this does: SELECT TSTZRANGE(ts, te) FROM test; Bug? Niggle? Can anyone explain to me why this is? To me, it's obvious what I want to do with the first statement - ideas, pointers, URLs, whatever welcome. TIA and rgs, Pól...
