Backend db as postgresql

I found it difficult to install mariadb, which causes many issues, if we have mysql already.

Tried hardly and installed mariadb and erpnext. But the experience is hard.

Seems fresh install of mariadb is good.

Why mariadb is chosen? Is there any plan to support postgresql in future?

as far as I know the anser (still valie 21.07.12) is to be found here
