Forum OpenACS Development: Re: Towards OpenACS 5.9
None, is my guess.
Back when I was maintaining Oracle support, did you ever offer to help pay for my time? Or, when the subject was ever raised, did you just post as you have posted now: "we need oracle support, don't drop it!"
"Should you care about this? About our specific needs, perhaps not. But I hope it least illustrates how the "legacy" feature of good support for both Oracle and PostgreSQL may be of more value than the typical PostgreSQL-only OpenACS user appreciates."
Sure, valuable to you and other freeloaders. But the reality is that for over a decade, almost all of the financial and programmer resource support has come from those using PG.
