pg_dumpall with individual output files per database?

Hi everyone,

I need to backup multiple host with multiple Postgres databases each.
In all of those cases I'm interested to backup all databases, which
makes pg_dumpall a natural choice at first glance. Though, from my
understanding of the docs that is only capable of storing all
databases per host into one single file.

That's not a too good approach for my databases, because some of those
store files with few GiB in size for legacy reasons. I would like to
avoid creating one large file only which then mixes those
file-databases with others containing less or different types of data.

So, is there some option I'm missing telling pg_dumpall to dump into
individual files, simply named after e.g. the dumped databases?

If not, was a feature like that discussed already or what's the
reasons to not do that? There are a lot of search results how to dump
all databases with lots of different scripting approaches. Many of
those could simply be avoided with pg_dumpall supporting that
already.

Tools like BorgMatic making use of pg_dumpall might benefit of such a
feature as well:

Thanks!
