It looks like there's an sh3el package for PostgreSQL on NetBSD here,
so whoever maintains that might be in touch:

https://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/databases/postgresql14-server/index.html

It's funny to think that you probably could run modern PostgreSQL on
the Sun 3 boxes the project started on in 1986 (based on clues from
the papers in our history section) if you put NetBSD on them, but
you'd probably need to cross compile due to lack of RAM.  The grammar
in particular.
