Review comment:
We need to add more test to get sure that correlated queries are planned
and executed properly. So let's provide a bunch of planner + integration tests
to verify:
- correlated queries in SELECT list (simple projection, aggregates)
- correlated queries as part of predicate (=, between, some/any, all, in,
exists)
- correlates in table functions (currently presented by `system_range`
function)
It would be nice to cover cases with multiple correlated variables.
