I've thought about that and would be OK to restrict things with this
suggestion if you'd prefer it. However, I could not decide in favor
of it as using a psql \dP+ >= v18 gives the possibility to show the
AMs of partitioned indexes, as these are also part listed in \dP. So
I've found that useful in itself.
