pg_restore 8.x to postgreSQL 9.x functions and triggers aren't created

Hello,

We have two postgreSQL servers that are in the latest 9.x as testing, but when we use pg_dump and pg_restore, our functions and triggers are never copied to postgreSQL Server 9.x.

This is how we restore:

data=`date +%Y_%m_%d`
pg_restore -c -i -h 192.168.0.9 -p 5432 -U postgres -d globalgest -v "/Users/montx/documents/BackUp/globalgest/globalgest_"$data

we have only two warnings:
...
pg_restore: dropping FUNCTION rowsaffected()
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 32; 1255 36705 FUNCTION rowsaffected() postgres
pg_restore: [archiver (db)] could not execute query: ERROR: function public.rowsaffected() does not exist

pg_restore: dropping FUNCTION repairassentamentsnumero(integer)

pg_restore: dropping FUNCTION increment_lock_version()

pg_restore: dropping FUNCTION getserialnumber(integer, integer)

pg_restore: creating FUNCTION updatecompte11(integer)
pg_restore: creating FUNCTION updatecompte3_5(integer)

pg_restore: creating TABLE audit
...

when restoring the same file to any of our postgreSQL Servers 8.x we have no problems.

thanks,
