1. PG17 regress sanity: fix diffs in multi_router_planner, …

   multi_router_planner_fast_path and query_single_shard_table
   
   Restore the expected DEBUG error messages from the router planner.
   In the case of query_single_shard_table the diffs are because of
   PG17's ability to pull up correlated ANY subqueries (*). The fix
   is to inhibit pull up with a volatile function.
   
   In the case of multi_router_planner and multi_router_planner_fast_path
   the diffs are because of PG17's ability to remove redundant IS (NOT)
   NULL expressions (**). The fix is to adjust the table definition so
   the column used for distribution is not marked NOT NULL.
