- Commit: 172259afb5
- Original report
- Fix discussion
- Once this issue is fixed, we need to enable dumping statistics and comparing them in pg_upgrade/002_pg_upgrade.pl. The patch for the same is posted in the thread.
Decisions to Recheck Mid-Beta
- Enable data checksums by default
- Commit: 04bec894a0
- Data checksums have been enabled by default. pg_upgrade cannot upgrade between non-checksum and checksum instances, so some additional steps are required by the user. Check whether the upgrade experience is tolerable and sufficiently documented. See the following list of threads that might be enhancing the end user experience:
- fixing tsearch locale support
- Commit: fb1a18810f0
- Text search locale support has been updated and integrated into the common locale framework. Possible upgrade issues should probably at least be noted in the release notes.
- Enable statistics in pg_dump by default (Jeff Davis)?
- decide what io_method to default to (Andres Freund)
- Commit: 247ce06b883
Older bugs affecting stable branches
Live issues
- Incorrect results for bitmap heap scan.
- Certain Bitmap Heap scans only test the visibility map before returning tuples. This can conflict with VACUUM removing tuples, thus causing more tuples to be returned from the scan than what are actually visible.
- Incorrect results for (SP-)GIST index-only scans
- Similar issue like the above.
