Hi.
While reviewing the row pattern recognition,
I noticed that the IGNORE NULLS and RESPECT NULLS clauses can be specified for
normal functions (prokind == 'f').
create or replace function dummy2(int) returns bigint AS $$ BEGIN
RETURN $1; END$$ STABLE LANGUAGE plpgsql;
select dummy2(1) IGNORE NULLS;
select dummy2(1) RESPECT NULLS;
This seems unexpected?
Also https://git.postgresql.org/cgit/postgresql.git/commit/?id=25a30bbd4235a49c854036c84fe90f2bc5a87652
Obviously, RESPECT NULLS and IGNORE NULLS can appear in SELECT query,
since they are dedicated keywords, shouldn't they be mentioned in
select.sgml?
