See convert() and friends here:

  http://www.postgresql.org/docs/9.0/interactive/functions-string.html#FUNCTIONS-STRING-OTHER

That will issue an error when the text can't be converted, but you could
have a plpgsql function catching the exception for you and returning
false. Won't be very fast, but will do the job.
