If someone doesn't copy over the metadata from pg_shard to CitusDB, but sets use_citusdb_select_logic to true, in CitusDB we treat all pg_shard tables as local tables and read the empty table on the master node, returning 0 results.
This is minor, but can be a usability issue with CitusDB/pg_shard integration.
