With 7.4 I'm finding upgrading to be easier. I'll likely upgrade out production servers to 7.4.0 when it comes out and wind up skipping 7.3 altogether.
Sure but I talking about people who are running 7.3 and are happy with it. The reality is that for probably 95% of the people
out there , there is no reason for 7.4. When you have existing system that works... why upgrade? That is one of the benefits
of Open Source stuff, we no longer get force into un-needed upgrade cycles.
We use PostgreSQL for everything, and I don't have any inclination to upgrade to 7.4 except that it is 7.4. I only have two
customers that will see any real benefit from going to 7.4. The rest are going to stay on 7.3 because they don't want:
A. The downtime B. Unknown or unexpected problems C. A brand new database D. Migration costs
When you deal with the systems I do, the cost to a customer to migrate to 7.4 would be in the minimum of 10,000-20,000 dollars.
They start to ask why were upgrading with those numbers.
That is not to say that 7.4 is not worth it from a technical sense but for my customers, "If it ain't broke, don't fix it" is a mantra and
the reality is that 7.3 is not broke in their minds. There is limitations pg_dump/pg_restore has some issues, having to reindex the database
(which 7.4 doesn't fix), vacuum (which 7.4 doesn't fix) but my customers accept them as that.
Your mileage may vary but I can only talk from my experience.
Sincerely,
Joshua D. Drake
