We have around 10 different partition tables for which the partition maintenance is done using pg_partman extension. These tables have foreign key dependency between them. We just called partman.run_maintanance_proc() through pg_cron without any parameters and it was working fine. So we can see only one entry in the cron.job table. And it runs daily once.
It was all working fine and we were seeing the historical partition being dropped and new partitions being created without any issue. But suddenly we started seeing, its getting failed with error "ERROR: can not drop schema1.tab1_part_p2023_12_01 because other objects depend on it"Have you changed version lately of PG, pg_cron or pg_partman? Or maybe what pg_cron or pg_partman depends on?
No version change, but we updated the part_config to set premake from 30 to 60 for all the tables. But not sure how that impacted this behavior.
However, do you think, we should better control the order of execution rather letting postgres to decide it's own, considering there is no such parameters for this ordering in part_config? And in that case which approach should we use out of the two i mentioned. Or any other strategies, should we follow, please advise?
