Re: pg14 psql broke \d datname.nspname.relname

I understand Tom's position to be that the behavior should be changed back,
since it was 1) unintentional; and 2) breaks legitimate use (when the datname
matches current_database).

I think there's an easy answer here that would satisfy everyone; two patches:
0001 to fix the unintentional behavior change;
0002 to reject garbage input: anything with more than 3 dot-separated
     components, or with 3 components where the first doesn't match
     current_database.

0001 would be backpatched to v14.

If it turns out there's no consensus on 0002, or if it were really hard for
some reason, or (more likely) nobody went to the bother to implement it this
year, then that's okay.

I would prefer if it errored if the datname didn't match the current database.
After all, it would've helped me to avoid making a confusing problem report.
