Compare Source

This release contains performance improvements and bug fixes since
the 2.14.2 release. We recommend that you upgrade at the next
available opportunity.

In addition, it includes these noteworthy features:

• Support time_bucket with origin and/or offset on Continuous Aggregate
• Compression improvements:
  • Improve expression pushdown
  • Add minmax sparse indexes when compressing columns with btree indexes
  • Improve compression setting defaults
  • Vectorize filters in WHERE clause that contain text equality operators and LIKE expressions

Deprecation warning

• Starting on this release will not be possible to create Continuous Aggregate using time_bucket_ng anymore and it will be completely removed on the upcoming releases.
• Recommend users to migrate their old Continuous Aggregate format to the new one because it support will be completely removed in next releases prevent them to migrate.
• This is the last release supporting PostgreSQL 13.

For on-premise users and this release only, you will need to run this SQL script after running ALTER EXTENSION. More details can be found in the pull request #​6786.
