psql (16.3)
Type "help" for help.

zabbix=# CREATE EXTENSION IF NOT EXISTS timescaledb;
FATAL:  extension "timescaledb" must be preloaded
HINT:  Please preload the timescaledb library via shared_preload_libraries.

This can be done by editing the config file at: /var/lib/pgsql/16/data/postgresql.conf
and adding 'timescaledb' to the list in the shared_preload_libraries config.
        # Modify postgresql.conf:
        shared_preload_libraries = 'timescaledb'

Another way to do this, if not preloading other libraries, is with the command:
        echo "shared_preload_libraries = 'timescaledb'" >> /var/lib/pgsql/16/data/postgresql.conf 

(Will require a database restart.)


server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.
