Hi.  Is there a way with to_char to suppress a decimal point, like a leading or trailing 0, so that integers will not have them, but non-ints will?  I'm hoping I'm missing something easy.  Thanks.

SELECT val,to_char(val::decimal(6,2),'FM999,999D99') FROM

( SELECT 1 AS val UNION SELECT 1.05 AS val) foo;

 val  | to_char 

------+---------

    1 | 1.

 1.05 | 1.05

Not seeing a native way to do so - and I'd question doing so as a general rule - though you know your domain.  If you must have this you will want to utilize regexp_replace to identify the situation and replace it.  A simple "\.$" check and a substring would work also.
