Fix segfault in UNION queries with top-level ordering #6957

Closed svenklemm closed 1 month ago

svenklemm commented 1 month ago

We can't just filter the equivalence member based on em_is_child as our hypertable might not be top-level equivalence member.

Fixes #6925

Even though this was reported as happening only after upgrade to 2.15.0 earlier versions of timescaledb are affected by this as well.

Looks like the codechange leading to this was introduced in 2.14.0
