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.
I setup a server running postgresql-server-9.2.10-2.el7_1.x86_64. After restoring my databases form a system running postgresql-server-8.1.23-10.el5_10 (created with pg_dumpall), several blank databases/entries were created.
When I list the database from the command line it shows several entries like:
| | | | | =T/postgres
After importing the databases is there a cleanup command of some sort?
These blank databases/entries do not show in PhpPgAdmin, yet my backup script tries to backup a database called “|”
Is this behaviour, after you have imported the databases and ANALYZE cluster ?. By-chance if you have missed to performe ANALYZE on post import, please do it.
Did you run the 9.2 version of pg_dumpall or the 8.1 version to create your original dump file? You should run the 9.2 version on the 8.1 database if possible.
