The following bug has been logged on the website:

Bug reference:      13687
Logged by:          Stepan
Email address:      stepanperlov@gmail.com
PostgreSQL version: 9.4.5
Operating system:   Ubuntu 14.04.1 LTS
Description:

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

​What do you see happening and what do you think should happen (and why)?

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"}'
