This patch adds support for a new SQL command: ALTER SUBSCRIPTION ... REFRESH SEQUENCES This command updates the sequence entries present in the pg_subscription_rel catalog table with the INIT state to trigger resynchronization. In addition to the new command, the following subscription commands have been enhanced to automatically refresh sequence mappings: ALTER SUBSCRIPTION ... REFRESH PUBLICATION ALTER SUBSCRIPTION ... ADD PUBLICATION ALTER SUBSCRIPTION ... DROP PUBLICATION ALTER SUBSCRIPTION ... SET PUBLICATION These commands will perform the following actions: Add newly published sequences that are not yet part of the subscription. Remove sequences that are no longer included in the publication. This ensures that sequence replication remains aligned with the current state of the publication on the publisher side. Note that the actual synchronization of sequence data/values will be handled in a subsequent patch that introduces a dedicated sequence sync worker.
