btree_gist, gint4_union
In contrib/btree_gist/ I see:
CREATE FUNCTION gint4_union(bytea, internal)
RETURNS int4
AS 'MODULE_PATHNAME'
LANGUAGE 'C';
but gint4_union does this:
INT4KEY *out = palloc(sizeof(INT4KEY));
[...]
PG_RETURN_POINTER(out);
Is the int4 return type declared above a bug?

Must be 'internal'. It's not a bug :) because this function is GiST interface
member
and itsn't any nessesarity to call it by hand.
