As promised, here is a diff to the pg_proc.c file which I applied
to allow multiple set valued attributes to be inserted in a
single query.  I have not run the regressions since I changed this,
but have seen no ill effects in my work.  For those who missed the
original question, appends of the form:

append lines ( p1="retrieve (points.all ) where points.id=1, 
	p2="retrieve ( points.all ) where points.id=2" ) \g

fail with the error

	ProcedureDefine: Procedure zyxset already exists with the same arguments.

Below is a diff for build/src/backend/catalog/pg_proc.c
