I'm not an expert on this, but I will tell you what I know. From what
I understand, partitioned tables and associated triggers are created
for date ranges ahead of time (before the date when the partition data
come into existence). Table creation is handled through CRON jobs and
scripts.
The following archived thread illustrates what one person did to
develop automatic creation of table partitions:

The above mentioned email may give you a workable solution.
