This has been brought up a few times in the past:
http://www.postgresql.org/message-id/CAAZKuFZF5=raA=RLncqEg_8GsJ9vi4_E-fi1aOmK4zP+dxcx4g@mail.gmail.com
http://www.postgresql.org/message-id/EC26F5CE-9F3B-40C9-BF23-F0C2B96E388C@gmail.com

Any chance it could be fixed? I can't figure out a way to easily let
javascript applications parse json timestamps generated by postgresql in
row_to_json() statements.
