That statement is false:

regression=# select 1234.000::numeric;
 numeric  
----------
 1234.000
(1 row)

I'm not sure offhand what is the easiest way to suppress trailing
zeroes, but casting to plain numeric is not the route to a solution.

Really this is a textual formatting problem.  You might find that the
best bet is something with trim() or a regexp.  The trick would be
not removing zeroes that are significant ...
