      Expected:
      zabbix=# SELECT drop_chunks('history', 1611234923);
      drop_chunks
      -------------
      (0 rows)

      In TimeScaleDB docs https://docs.timescale.com/latest/api#drop_chunks we see:

      SELECT drop_chunks('conditions', INTERVAL '3 months');

      The first argument is a table, and second argument - interval.

      And in Zabbix source code we see:

      zabbix-5.2.3/src/zabbix_server/housekeeper/housekeeper.c:

      result = DBselect("SELECT drop_chunks(%d,'%s')", keep_from, rule->table);

      Here on the contrary, the first argument is a interval, and second argument - table.

       

      As result we get error:

      zabbix=# SELECT drop_chunks(1611234923,'history');
      ERROR: invalid hypertable or continuous aggregate
