On the old system running 8.1 I am executing the pg_dumpall command as shown in the script. I then copy the file to the new server running 8.4 and run this command "psql -U postgres -f postgresql-all-10-10-2013_04-07-databases postgres"
The log is reporting database name_of_database does not exist create database name_of_database There is an error reporting for latin1 encoded databases : psql:pgdbs:167: ERROR: encoding LATIN1 does not match locale en_US.UTF-8 DETAIL: The chosen LC_CTYPE setting requires encoding UTF8. Any latin1 encoded databases do not get created. Thanks I am using 8.4 just because it's what gets installed with CentOS6.4.

When I restore the databases, with the commands below, only the databases are created, no tables and no data is restored. * gunzip postgresql-all-10-10-2013_04-07-databases.gz * psql -U postgres -f postgresql-all-10-10-2013_04-07-databases postgres The above works between two different servers that both run 8.1. What am I missing to restore all my databases with tables and data from 8.1 to the new 8.4? Thanks It would be helpful to see any error messages from the client or the log. But lacking that info, my first suggestion is to be sure that you are using pg_dumpall from the *new* version of PostgreSQL and *not* trying to restore a dump taken with an old version into the new version of the database. It's not clear which versions of the clients you are using from your message but I'm guessing this may be part of your issue. The second suggestion is to upgrade to a recent version of PostgreSQL. If you are going to the effort of an upgrade it seems like a bit of a waste of time to go to 8.4 which is only supported for a few more months when you could move to 9.3 and have a version supported for nearly five more years plus all the feature and performance improvements that have been made in the several years since 8.4 was released. Cheers, Steve
