Is there a way to use postgres rather than mysql as the backend db for concrete5? The server where I have most of my sites hosted on only has postgres as its the sys admin's db of choice.

I respect that, but can't install concrete5 on it :(

Can I use postgres and how? Can anyone help me figure it out? I am not a saavy php/db developer, more of a front-end developer that knows enough to get into trouble.

Thanks.
