Well, you can always do ad-hoc materialized views ... I'm coding some now.

However, better matview management is currently under development. We had a Google Summer Of Code project to write code to manage the updating of materialized views. In a couple of releases, we might have matviews as good as Oracle's.

Of course, if you're a PostgreSQL user and you want better matview support, then we could really use your help developing it.

JD,

You're absolutely correct that such a comparison would be a real asset to users. However, it would also be a Herculean task. Several people have tried to do similar things, but the number of indexes you need to compare (features, reliability, performance, etc.) is too large. And some things are so different it's hard to compare them meaning fully. Imagine trying to do a head-to-head comparison of all OSes in every way.

Here's a few comparison links, but they just scratch the surface:

PostgreSQL *must* be the leading open source SQL database, now. People are bashing us on Slashdot. That's always a sign of success.

Thanks, guys!

Why not just use .NET with PostgreSQL? You can put whatever you want on the back end.

Or you could use Once:Radix or Servoy, both of which integrate with PostgreSQL.
