Review comment:
Perhaps it's better to extend AbstractBasicIntegrationTest to get rid of
boilerplate code

Review comment:
Too complicated query. To reproduce the problem it's enough just two
columns in the table (PK, COL0) and descending index by COL0, with this query:
`SELECT PK FROM TBL1 WHERE col0 IN (SELECT col0 FROM TBL1)`
