Actually there were two issues:
- missing \n, so it picked the wrong query anway
- no unique identifier, hence it may works incorrectly (and actually,
event clickhouse-test script executes 'SELECT 1' query)
Also some of them can be even more simplified, since the system.*_log
are empty most of the time there should not be any conditions at all
(i.e. `query` LIKE and so on).
