  • Due to false-positive crc match it was possible to erroneously reuse file during incremental restore, which could break pg_catalog relations relying on for filenode mapping if they were subject to VACUUM FULL or REINDEX operations before backup. This is fixed now.
  • A race condition between reader and writer in acquiring the backup exclusive lock is removed.
  • File descriptor leak in the backup shared lock is fixed.


  • The remote agent API is now stable across the same minor version starting with 2.4.9, which makes pg_probackup installations more robust towards version drift. Requested by Alex Ignatov.
  • It is now possible to restore and validate a backup from a read-only filesystem. Requested by Mikhail Kulagin.
  • Backup shared locks are now released at the process exit.
