pgsql: Use context with correct lifetime inhypothetical_dense_rank_fin - Mailing list pgsql-committers

Use context with correct lifetime in hypothetical_dense_rank_final.

The query lifetime expression context created in
hypothetical_dense_rank_final() was buggily allocated in the calling
memory context. I (Andres) broke that in bf6c614a2f2.
