So much time since my last post !
I apologize to all of you who sent me messages I didn’t answer.
I’ve had much work in the last months and mainly off the Net, but I’m back on track and already started to enhance PG4WP to correct some bugs and add new features.
If you try the current development version it now includes support for PostgreSQL 9.1+ « out of the box », but it needs testing.
I’ve also tested fresh installing and upgrading to WP 3.3.2 (and also 3.4-beta4) and all seemed to go well.
I’ve had some contacts about WPMU, so I’ll try to work on it after the next release of PG4WP (which should come in the next few weeks).
