As TimescaleDB has quite a lot minor version releases, you often come to a point that you have to update the TimescaleDB version you’re using.<\/p>\n\n\n\n

Before updating the version, always check which TimescaleDB versions are compatible with your PostgreSQL version. If your TimescaleDB version is too new<\/em>, you will first have to upgrade your PostgreSQL server. A great page to visit and check the compatibility is this one: https:\/\/docs.tigerdata.com\/self-hosted\/latest\/upgrades\/minor-upgrade\/<\/a><\/p>\n\n\n\n

First let’s check the current version of PostgreSQL:<\/p>\n\n\n\n

su - postgres\npsql -X -d zabbix -c \"SELECT version();\"<\/code><\/pre>\n\n\n\n
This should give an output like this:<\/p>\n\n\n\n
-------------------------------------------------------------------------------------------------------------------------------------\n PostgreSQL 16.10 (Ubuntu 16.10-1.pgdg24.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0, 64-bit\n(1 row)<\/code><\/pre>\n\n\n\n
After this check the current version of TimescaleDB:<\/p>\n\n\n\n
psql -X -d zabbix -c \"\\dx timescaledb;\"<\/code><\/pre>\n\n\n\n
This should give an output like this:<\/p>\n\n\n\n
                                              List of installed extensions\n    Name     | Version | Schema |                                      Description                                      \n-------------+---------+--------+---------------------------------------------------------------------------------------\n timescaledb | 2.21.3  | public | Enables scalable inserts and complex queries for time-series data (Community Edition)\n(1 row)\n<\/code><\/pre>\n\n\n\n
Before upgrading the installed TimescaleDB extension for your Zabbix database, you’ll have to check which extension version is available. This can be done with the following SQL-query:<\/p>\n\n\n\n
psql -X -d zabbix -c \"SELECT default_version, installed_version FROM pg_available_extensions WHERE name = 'timescaledb';\"<\/code><\/pre>\n\n\n\n
The output should be something like this:<\/p>\n\n\n\n
 default_version | installed_version \n-----------------+-------------------\n 2.22.0          | 2.21.3\n(1 row)<\/code><\/pre>\n\n\n\n
When all is great, you can perform the TimescaleDB extension upgrade. Type the exact version in which was displayed above in the column default_version<\/em><\/strong>:<\/p>\n\n\n\n
psql -X -d zabbix -c \"ALTER EXTENSION timescaledb UPDATE TO '2.22.0';\"<\/code><\/pre>\n\n\n\n
After this is done, check which version of the TimescaleDB extension you’re running right now:<\/p>\n\n\n\n
psql -X -d zabbix -c \"\\dx timescaledb;\"<\/code><\/pre>\n\n\n\n
Now you can see the new version of the extension is activated!<\/p>\n\n\n\n
Name     | Version | Schema |                                      Description                                      \n-------------+---------+--------+---------------------------------------------------------------------------------------\n timescaledb | 2.22.0  | public | Enables scalable inserts and complex queries for time-series data (Community Edition)\n(1 row)<\/code><\/pre>\n\n\n\n
As the releases of TimescaleDB are very often, Zabbix server sometimes will fail to start as you’re running a version which isn’t supported by Zabbix. To run Zabbix server on a bleeding edge<\/em> version of the TimescaleDB extension you will have to change a setting in your zabbix_server.conf<\/em><\/strong>, this can be set like this:<\/p>\n\n\n\n
AllowUnsupportedDBVersions=1<\/code><\/pre>\n\n\n\n
After you’ve performed all the previous steps, you’re running a new TimescaleDB extension for your Zabbix server!<\/p>\n","protected":false},"excerpt":{"rendered":"
