The syntax is the same as with CREATE TABLE ... PARTITION OF, e.g.
ALTER TABLE parent ATTACH TABLE part FOR VALUES WITH (MODULUS m, REMAINDER r);

There's only one (modulus, remainder) tuple in the partition bound
definition for hash partitions, and always only one partition bound
specification per partition.
Maybe what you actually want is a DEFAULT partition (specified as
PARTITION OF parent DEFAULT), or maybe a completely different approach?
