I agree with your comment. Thanks.

I thought all tests related to meta-commands exist in psql.sql, but I
realize it's not true. For example, the test of \dRp does not exist in
psql.sql. Therefore, I moved the regression test of \dX to stats_ext.sql
to avoid the test failed in parallel.
Attached patches is following:
However, I feel the test of \dX is not elegant, so I'm going to try
creating another one since it would be better to be aware of the context
of existing extended stats tests.
