timescale/timescaledb 2.32.0 on GitHub

This release includes security fixes, performance improvements, and bug fixes since 2.31.0. As part of our ongoing proactive security reviews, this release includes a larger set of security fixes than usual. We recommend that you upgrade as soon as possible.

Loader Changes
For the loader changes take effect a PostgreSQL restart is required.

#10966 Check database ownership before stopping or restarting background workers on database commands
#10983 Run the background worker scheduler as the database owner instead of as superuser

Features

#10864 Improve continuous aggregate refresh performance by updating the watermark once per batch
#10878 Enable Adaptive Integer Compression (AIC) by default
#10927 Remove user switching when allocating ids from the internal catalog sequences
#10953 Allow database owners to start, stop, and restart background workers without superuser
#10960 Run the telemetry job as the database owner instead of the role that installed the extension
