We've decided to upgrade our PostgreSQL production servers. First task is
remove an old v7.14 version. It was supposed to be upgraded to a v8.4
server. The server was installed, several databases where released here but
v7.4 was never migrated. The plan is pg_dump this database and psql it to
existing 8.4 server. After this, we'll pg_upgrade.
If you doing dump-restore anyway, why not restore into v11 rightaway?
Since it's recommend to run the newer pg_dump on the older database, I've
got to wonder if v11 pg_dump can read the v7.4 on-disk structures.
