I think adding a test here would be worthwhile -- publications.sql
already defines the tables and publications, and a test would help catch
regressions caused by future refactoring.

What about this?

I previously said the issue was in \d+, but it’s actually in \d. I’ve
updated the commit message accordingly.

db=# \d testpub_rf_schema2.testpub_rf_tbl6

Thanks!
