Both the 8.3.8 and 8.4.1 releases have been updated and released today. Downloadable from here, these two installers are the wrapped around the latest PG cores, but also include some enhancements to the Preference Pane that make it more Snow Leopard friendly.
This release also marks the move to a new directory structure to allow multiple versions and a quick way to switch between them in the form of the pg_set_version.sh shell script. Eventually this will be part of the Preference Pane.
So, back a few months ago, some comments were made that this project not continue due to the availability and tacit 'official' status of the EnterpriseDB installers. That raised some concerns among some users. There has also been a fair amount of email traffic over the delay in getting 8.4.1 and 8.3.8 released.
Let us clarify some things. This project is built and managed by two people. I won't speak for the other person, but I can an will say that this is not something that either of us make any real money off of. We have done zero (paid) consulting with regards to this project. Donations and advertising revenue (which have been quite open about) has generated roughly $500 above the raw hosting expenses ($120 / year) in the 5 years this project has been active. This is not per year, this is total. Needless to say, we keep doing this because we want to.
So, the future is simple. We do it because we want to, but sometimes the release schedules will have to float around the real life schedules and jobs that allow us to do the work. The only way this becomes a full time deal is we could find enough people to make significant ($1000 or better) annual contributions to allow one or both of us to switch to PostgreSQL for Mac as a full time job. Doing so would allow us to fulfill our personal dreams of building the PostgreSQL environment into a rich GUI environment that would compete with MSSQL favorably.
So no, the project is not dead, but it does ebb and flow as time allows and permits, and in that time we continue to work towards finding ways to make our vision come true. The other hurdle, is that we want it to remain Open Source and as free as possible, which has been the deal killer on both prior proposals for us to take full time jobs to enhance this project.
