Re: change JSON serialization for BIGINT?

Is there a way to have Postgres serialize BIGINT as a string rather than number in JSON?  By default it does this:


select row_to_json(row(500::bigint));
 row_to_json 
-------------
 {"f1":500}

But I want it to do this (note that "500" is quoted):

select row_to_json(row(500::bigint));
 row_to_json 
-------------
 {"f1":"500"}
