I was waiting for a decent Windows-installable version of PostgreSQL, and it was announced that 7.5 would have such a thing. There’s no 7.5 release, but an 8.0 beta! Still no native Windows installer, but there is one here.
The good thing is, that this release has/will have a native Windows server process, installable as a service. It has point-in-time recovery. It supports tablespaces, to ease diskspace-management/layout. It has savepoints, to fully control whether transactions fail partly or completely. You can change column datatypes now. And the list goes on. Read the full version here.
I’ll definitely check this one out later this week.
