Hi Adam,
I remember having trouble going from postgres 7.2 to postgres 7.3 when i
upgraded distros.
I was using redhat at the time.
I think, I uninstalled the new version (7.3) - which was failing to
start because of the older format databases I was using - and
reinstalled the old version (7.2).
Running as 7.2, I then dumped the databases I had been using:
pg_dump -U user_name database_name >dump_file
I must have taken a backup of the raw files too as insurance and then
deleted them and installed 7.3 as a completely clean install.
Then after the new postmaster was up and running, I reinstalled the
databases with something like
psql -U user_name database_name <dump_file
(You have to create the database first using 'createdb' at the shell or
CREATE DATABASE as the sql prompt.)
I don't know if that's the way it's meant to be done but I got there in
the end.
Cheers,
Daniel.
