Hi,
I have a question in mind. I have read http://www.postgresql.org/docs/8.4/static/migration.html
and still it is not clear for me. The question is that
http://www.postgresql.org/docs/8.4/static/migration.html states first do a
pg_dumpall (which contains postgres db) Just in case I have made
pg_dumpall --clean --inserts (--insert is not required though) on Pgsql 8.2
Then on target machine which contains 8.4 I have issued
psql -f backup postgres
command.
My question here is that with import command my backup file contains postgres db which may NOT be compatible with 8.4 since this
dump is for 8.2
So how this incompatibility is resolved? AFAIK major versions are not compatible and requires dump/restore but how postgres table (aside from other db that we have created) is handled?
Regards.
