My advice is to move the table creation from a trigger to a nightly cron job. I have one that runs each night that checks for the existence of the needed tables and creates new ones for up to a month in advance and emails me the results. that way if it starts failing I've got 30 days to get things fixed. Then another script runs that creates my new triggers to work with the new partitions.
Too many race conditions and performance issues with using dynamic DDL to create partitions.
My partitions are based on a foreign key. I would be creating child tables when a new entry is made in the parent table.
