Re: migrating to 9.2 created blank dbs

Going by your package name, I'm assuming you're running Red Hat or CentOS.
Running both 8.1 and 9.2 at the same time on that OS could be a bit tricky
and this isn't really the proper medium for discussing how to do so.

What you could do is copy the 9.2 pg_dumpall binary from the machine you
have it installed on now and put it on the other machine. As long as
they're the same OS/architecture that should work fine. The other option is
to open up a network connection between the two systems and allow
pg_dumpall from the 9.2 system to connect to 8.1 on the old system.
