I agree with that assessment, at least in its present state. For example:

regression=# select * from unnest(array[[1,2,3],[4,5,6]]); unnest
--------      1      2      3      4      5      6
(6 rows)

Per SQL99 I think that ought to return something like:

-- output faked
regression=# select * from unnest(array[[1,2,3],[4,5,6]]); unnest
-------- {1,2,3} {4,5,6}
(2 rows)

Problem is that a polymorphic SRF cannot (currently at least) both 
accept and return type anyarray.
