What do you need the trigger for? And what does the trigger do? If you insert into the parent table, Postgres will automatically store the row in the appropriate partition. Apart from the need to upgrade because row triggers on a partitioned table require Postgres 11, you might want to consider upgrading to at least Postgres 12 anyway, as there were substantial partitioning improvements in 11 and 12 (performance and usability wise)
