Clearly a bug --- the wrong type OIDs are being passed down to
array_append. It should be told that it's getting called as
(angle_vectors[], angle_vectors) returns angle_vectors[]
but what it's actually getting told is
(vector, angle_vectors) returns vector
which naturally makes it spit up because "vector" isn't an array type.
I don't think control ever reaches your custom finalfunc at all.
Probably somebody fat-fingered this while refactoring code in the
aggregate/windowfunction area. Possibly me :-(. Haven't found
exactly where things are going off the rails, but it's clearly
a PG bug. Thanks for the report!
