Sorry, forget add output:

SELECT row_to_json(t) FROM (SELECT '-infinity'::timestamptz AS time) t

OUT: '{"time":"infinity"}'
MUST: '{"time":"-infinity"}'

In postgresql 9.3 it returns '-infinity'.
Problem with cast timestamp to string in row_to_json function.

SELECT row_to_json(t2) FROM (SELECT time::text FROM (SELECT
'-infinity'::timestamptz AS time) t) t2
returns '{"time":"-infinity"}'
