Safe to rename a partitioned table

[sposerina]

I'm attempting to migrate an existing table to a native partitioned table managed by partman. Once the copy of the data from the existing table is complete I want to rename the partitioned table to the existing table. Is there any problem with renaming all the partitions, renaming the template table, and upating the row in part_config for the partitioned table to reflect the exising name? Any other concerns modifying the partman config tables in this manner?

I think you've covered everything there. Also make sure to update the template table name in the part_config table as well.

This document was my attempt at a process to convert an existing partition set to partman so hopefully it helps

Thanks for the confirmation. If I understand this correctly renaming contraints and partitions isn't necessary but is just good practice to keep everything clean. The only thing that needs to change is parent_name in the part_config, the name of the template table, and the column that references that table in part_config. If this data is wrong the partition manager will fail to create new partitions when maintenace is run.

I believe that's correct. Would still recommend testing first just to be sure.
