Release Notes Published

This release adds major new features since the 2.2.1 release. We deem it moderate priority for upgrading.

This release adds support for inserting data into compressed chunks and improves performance when inserting data into distributed hypertables. Distributed hypertables now also support triggers and compression policies.

The bug fixes in this release address issues related to the handling of privileges on compressed hypertables, locking, and triggers with transition tables.

Features * #3116 Add distributed hypertable compression policies * #3162 Use COPY when executing distributed INSERTs * #3199 Add GENERATED column support on distributed hypertables * #3210 Add trigger support on distributed hypertables * #3230 Support for inserts into compressed chunks

Bugfixes * #3213 Propagate grants to compressed hypertables * #3229 Use correct lock mode when updating chunk * #3243 Fix assertion failure in decompress_chunk_plan_create * #3250 Fix constraint triggers on hypertables * #3251 Fix segmentation fault due to incorrect call to chunk_scan_internal * #3252 Fix blocking triggers with transition tables

Thanks * @yyjdelete for reporting a crash with decompress_chunk and identifying the bug in the code * @fabriziomello for documenting the prerequisites when compiling against PostgreSQL 13
