Fix collation exposed for scalar function in FROM. One code path in addRangeTableEntryForFunction() neglected to assign a collation to the tupdesc entry it constructs (which is a bit odd considering the other path did do so). This didn't matter before commit 5815696bc, because nothing would look at the type data in this tupdesc; but now it does.
While at it, make sure we assign the correct typmod as well. Most function expressions don't have a determinate typmod, but some do. Per buildfarm, which showed failures in non-C collations, a case I'd not thought to test for this patch :-( Branch ------ master Details ------- https://git.postgresql.org/pg/commitdiff/4d02eb017e3c1268762fd1a10ec3c569515c047d Modified Files -------------- src/backend/parser/parse_relation.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-)
