Hi Andre Mazayev ,
Greetings!!
As of now, Azure Database for PostgreSQL Flexible Server supports TimescaleDB version 2.17.2 for PostgreSQL v17. Unfortunately, this means newer TimescaleDB versions like v2.21.x are not yet available on Azure.
No official ETA has been published for when TimescaleDB v2.21+ will be supported on Azure PostgreSQL Flexible Server.
The Azure release notes show that TimescaleDB updates are infrequent and lag behind the upstream TimescaleDB releases.
Hope this helps. Do let us know if you any further queries.
