Thread: pgsql: Cosmetic improvements in setup of planner's per-RTE arrays.
Cosmetic improvements in setup of planner's per-RTE arrays. Merge setup_append_rel_array into setup_simple_rel_arrays. There's no particularly good reason to keep them separate, and it's inconsistent with the lack of separation in expand_planner_arrays. The only apparent benefit was that the fast path for trivial queries in query_planner() doesn't need to set up the append_rel_array; but all we're saving there is an if-test and NULL assignment, which surely ought to be negligible. Also improve some obsolete comments.
