My application is for archiving. I'm using partitioned tables (each 100000 records) to keep a rolling archive of the last 10 million. I already need to setup a trigger function for inserting into the latest partition. What I'd like to do is automate the process of creating a new table with a name based off the record ID, a bigserial that is used to defining each partition. Whether its automated or not, every 100000 record inserts will require 3 actions: 1. create a new partition, 2. modify the insert trigger function, and 3. truncate and drop the oldest partition. A number of things complicate the process for me. I'm using a COPY statement to bulk insert a varying number of records that can occur at different intervals of time. Also, the application starts and stops at various times, so it must be able to initialize based on the state of the database on startup. Is there a way to dynamically create table names within a function based on a numeric value? I want to be able to name the partitions log_1, log_2, ..., log_x, where x is the record ID / 100000. I would also have to be able to truncate the same way, by dynamically specifying the name of the table to be deleted. Well, I appreciate the help, anyway.
