- Major bugfix: incorrect handling of badly compressed blocks, previously there was a risk to restore block in uncompressed state, if compressed size was equal or larger than BLCKSZ
- Impromevent: backup from replica >= 9.6 no longer need connection to master
- Workaround: wrong minRecPoint in PostgreSQL thanks to commit 8d68ee6(block from future), overwrite minRecPoint with latest applied LSN
- Impromevent: merge is now considered stable feature
- Impromevent: validation now use more conservative and paranoid approach to file validation, during validation pg_probackup also check block checksumm, make sanity check based on block header information and try to detect blocks from future
- New validate/restore options:
'--skip-block-validation' - disable aforementioned approach to file validation
- Multiple minor fixes
Note: For now there are tests only for Linix
Check physical correctness of restored instances:
Apply this patch to disable HINT BITS: https://gist.github.com/gsmol/2bb34fd3ba31984369a72cc1c27a36b6
export PG_PROBACKUP_PARANOIA=ON
Check archive compression:
export ARCHIVE_COMPRESSION=ON
Enable compatibility tests:
export PGPROBACKUPBIN_OLD=/path/to/previous_version_pg_probackup_binary
Specify path to pg_probackup binary file. By default tests use <Path to Git repository>/pg_probackup/
export PGPROBACKUPBIN=<path to pg_probackup>
Usage:
pip install testgres
pip install psycopg2
export PG_CONFIG=/path/to/pg_config
python -m unittest [-v] tests[.specific_module][.class.test]
