We had a similar request and we have written a postgresql function to concurrently detach old partition in version 15, unfortunately we cannot use concurrently inside a postgresql function. We have to apply a logic and run individual detach commands for each partition via pg_cron.On Tue, 9 Jul, 2024, 9:55 am Sathish Reddy, <sathishreddy.postgresql@xxxxxxxxx> wrote:Thanks for the advice.please help me on configure pg_cron schedule job trigger from postgres database to another database will run job

No concurrent operations can be called within a function's transaction block.See this issue for more information - https://github.com/pgpartman/pg_partman/issues/387If you need to detach concurrently, you will have to use some separate process to do it at this time. Not sure if that can be done with pg_cron since I'm not sure if that is also doing its own calls within a functional transaction.--
