Bug Fixes

DescriptionAddresses
Fixed a segfault in the consensus worker during rolling upgrade to 6.3.0 when bdr.enable_auto_sync_reconcile is on.

When bdr.enable_auto_sync_reconcile = on, an older-version node sending a reconcile_2pc_requests Raft upsert to a 6.3.0 node could cause a crash loop on restart. This setting is on by default in 6.x versions and off by default in 5.x versions.

Fixed bdr_init_physical failure when PGAA extension is present.

When scaling up a PGD cluster from a single data group to multiple data groups on deployments using the Postgres Analytics Accelerator (PGAA) extension, bdr_init_physical failed with no analytics lease found for database during the bdr.remove_unwanted_data() step. This issue only affected clusters initially provisioned with a single data group that were later scaled out.

Fixed user login attributes not replicated to peer nodes.

After a CREATE USER statement, the user's login attribute was not propagated to peer nodes, preventing login on any node other than the originating one. This fix ensures role login attributes are correctly included in replication.
