nice to see the safety net - just in case :-) I don't think I have I have heard anyone talk of dropping mysql support. I think that would be grossly premature. Jason is trying to build an installer with which bundle postgres. I am sure the same could be done with mysql. As far as dhis2-live is concerned it is (so far) not dependent on any of the three and I think it should remain that way. > --- > Regards, > Saptarshi PURKAYASTHA > Director R & D, HISP India > Health Information Systems Programme > > My Tech Blog: http://sunnytalkstech.blogspot.com > You Live by CHOICE, Not by CHANCE > > > On 3 March 2010 11:20, Jason Pickering <jason.p.picker...@gmail.com> wrote: >> >> I agree as well.
