When upgrading to Zabbix 7.0, the minimum version of TimescaleDB extension has been increased, thus you might encounter the following error if you’ve been conservative when upgrading the extension due to version mismatch.
Starting Zabbix Server. Zabbix 7.0.0 (revision 49955f1fb5c).
using configuration file: /etc/zabbix/zabbix_server.conf
TimescaleDB version 20902 is not officially supported. Recommended version is at least TimescaleDB Community Edition 2.10.0.
Zabbix Server stopped. Zabbix 7.0.0 (revision 49955f1fb5c).
To upgrade the timescaledb extension, you need to make sure you don’t upgrade to a non-supported version. For example with Zabbix 7.0 LTS released, the supported extension versions (2 Requirements (zabbix.com)) are between 2.10.0 to 2.14.0, with 2.15.x being the newest available release and is not supported by Zabbix.
Start with upgrading to a specific version, for example 2.14.2-el9.
dnf --showduplicates list timescaledb-2*
dnf install timescaledb-2-loader-postgresql-15-2.14.2-0.el9 timescaledb-2-postgresql-15-2.14.2-0.el9
Run the following command if prompted;
# timescaledb-tune –pg-config=/usr/pgsql-15/bin/pg_config
Restart the database-server and connect to it using -X to not load the extension (Timescale Documentation | Minor TimescaleDB upgrades).
systemctl status postgresql-15
systemctl restart postgresql-15
systemctl status postgresql-15
sudo -u postgres psql
To check the current database extension version, first connect to the database and then check the version;
psql (15.7)
