SILENT isn't a bad idea. It seems
I decided that it would be worth benchmarking this patch.
Specifically, I tested:
master, as a basis of comparison
checksum16_with_wallogged_hint_bits.v10.patch, page_checksums = 'on'
checksum16_with_wallogged_hint_bits.v10.patch, page_checksums = 'off'

If you know the type has been installed as an extension you can look at
the extension's content in pg_depend, much like \dx+ does, limiting to
only types whose name matches.
