there is one fundamental principle one follows in criticising/commenting on open source applications:
the developer gets to choose his platform and his tools. It is counter productive to give long arguments about his choice. He is not going to change especially after putting in a hell of a lot of hard work. Criticise the application - tear it to pieces, but respect his choice of the colour he uses to paint his bike shed.
I did not criticize the original developers choice of db. I commented on your views regarding sqlite. Neither does my reply imply in any way to forego the efforts already put in by Mr. Mane and his team in favour of sqlite. I only mentioned the advantages of sqlite in the same spirit as you displayed for postgresql.
If giving out correct information is what you object to, then this discussion is useless.
