Yes but how often does a major release come out? 17th Jan 2005 was the
first date of 8.0 according to the FTP site, with 8.1 out in November 2005.
If it takes a whole day to do a dump/restore, that's only one day out of
about 270 or more.

Plus in MS SQL Server, once you've moved on a version (e.g. 7 to 2000) you
can't go back - whereas in PGSQL you can just re-dump your data and revert
back to the previous version providing you're not using any features the
previous version doesn't understand - it gives much more flexibility and
more confidence in the upgrade.

Hello

Exactly this issue and that you have to make a 'full' dump/restore
between major release is a big minus I hear everywhere I explain/discuss
about postgres for 24/7 and big databases.

It would be wonderful to see a solution to these two 'problems' in the
future so postgres becomes an even better product than it is now.
