Postgresql and sql

Hey there. I have been lost in the ocean of backend options today, and am really impressed by Parse.
I’m a sql guy so would like to use sql in the backend. Is this possible? I mean:

1 - create tables by hand (and indexes, and pk, fk, triggers, etc.) and use those tables in Parse?
2 - makes queries using sql instead of learning a new dialect? for instance, send a sql query through rest api endpoint?

Thanks.

You can use Postgresql as database, but it is not recommended to create the tables by yourself and there is currently no way to write the sql queries yourself.

ok, thanks for your help.
