Samay Sharma and Jason Petersen have an announcement:
We are excited to launch
pg_timeseries: a PostgreSQL extension focused on creating a cohesive user experience around the creation, maintenance, and use of time-series tables. You can now use pg_timeseries to create time-series tables, configure the compression and retention of older data, monitor time-series partitions, and run complex time-series analytics functions with a user-friendly syntax. pg_timeseries is open-sourced under the PostgreSQL license and can be added to your existing PostgreSQL installation or tried as a part of the Timeseries Stack on Tembo Cloud.
Read on to learn more about how it works. The syntax and concepts do remind me a good bit of InfluxDB, as well.
