Hi!
We are using postgresql 8.3 in my work, and the need to migrate to
a newer version became urgent :)
I've been reading the release notes for versions 8.4 and 9.1, but
is not clear to me which problems I can have with version 8.4 or
9.1 from a dump 8.3
My boss thinks we would have fewer problems if we use the version
8.4, I believe that it is best to have version 9.1, and the number
of problems will be the same as in version 8.4
In favor of version 9.1 is that it will be supported until 2016.
What is the structural difference or what was the reason to have a
version 9 and version 8?
Please, could you help to give peace of mind to my boss and make
sure that the version we choose to be as smooth as possible
compatible with version 8.3?
indeed to restore the dump of the 83 in 9.1 had a bug in UTF-8,
will I have the same problem with the 8.4???
What will be the problems you have had to migrate from version 8.x
to the 8.4 or 9.1???
is it a good idea migrate to 9.1 rather than 8.4?
Perhaps, it would be a good idea to have a page on the postgresql
site which is titled: How to convince my boss to install latest
version. ;)
Farewell, and thank you for your help.
Regards.

Pg 9.2 is out real
soon
now; but for you, I think going to 9.1 is a better trade-off in
risks
and benefits.
The 9.1 version is far
faster and more reliable than 8.4, apart from having extra
functionality that may prove very useful. However, as has has been
noted elsewhere: there are incompatibilities between the version
you
are using now and 9.1, so you will need to rigorously check for
these.
Cheers,
Gavin
