I've also found your reference from the lists of 2019 to be the only
one referring to a regdatabase.
If it means that I will type less by not having to do joins with
pg_database, count me in.
The last time I recall we've discussed about a reg shortcut was
regcollation, which was mentioned as useful for dumps. Even if we've
finished by not using it in the dump, I tend to find these shortcuts
always useful.
For regdatabase, there would be at least two simplications related to
the dump of subscriptions, where we could switch the queries to the
new grammar for backend versions able to support the new grammar,
meaning that we could remove entirely these parts in 11~12 years once
the versions that do not support the new reg shortcut would be out of
scope. :D
