I'm in the same boat ... I have an input function I want to test, and so far I have failed to think of *any* sql construct that causes it to be invoked with other than -1 for the typmod. > but you definitely should have a "length conversion cast" > function in pg_cast if you expect to do anything useful with typmod. Ok, that's good to know (and I didn't until now). But back to the input and recv functions, which are both documented to have 3-arg forms that get typmods ... how would one test them? Is there any sql syntax that can be written to make them get passed a typmod? If I just write them with assert(typmod == -1), will anyone ever see a failure? -Chap -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
