ok , first thanks a lot for your responses, well
not my are doing this wrong castings, they are from ODBC
driver , my analisys was from server side, i mean, this
information is send from my aplication via ODBC to
postmaster .
For research propouses start the postmaster with debug level
3 and later ,recreate this queries with additional explain
clauses for analisis, the ::timestamp in syntax not in my
own code ok ? .
well questions i plan to change this castings , modifing the
database definition
numeroVia smallint -> to int4
fechaHora timeStamp(3) with timezone -> timeStamp(3) *

* milliseconds are very important to me, the aplication
register events at real time and millisecond are difference
into 2 events , application is multithread .

last question, is posible to make this changes whitout
download the database at all ? , the alter table ..... do
it?

pd: Sorry for my english , again ;)
