The attached tiny patch lets the to_json(b) routines convert objects
with array pseudotypes to json{b}. The main impetus for this came from
my trying to convert the annyarray columns in pg_stats to json and
finding that they ended up as text instead of json arrays. This way
to_json on these columns does what is expected.
