I saw that one; it's just syntactic sugar, just like list_nth_int and list_nth_oid, except it has only one possible callsite instead of a dozen like those others. I see no harm in that function, but no practical advantage to it either. Xid lists are a very fringe feature, there being exactly one place in the whole server that uses them. -- Álvaro Herrera 48°01'N 7°57'E — https://www.EnterpriseDB.com/
