I will start using postgress and latter a combination of postgress-and-mongodb or postgress-and-firebase etc etc.
The problem is i found a good udemy course on Postgress but that course name is "SQL and PostgreSQL" so that include SQL too, but i will use graphQl (obviously i will learn graphql after learning postgreSQL as I'm unable to find GraphQL-with-PostgreSQL).
So my Question is:
1. Will my time and effort of learning the part of SQL will be in vain?
2. Or Is it best advice to learn SQL first?
What I have tried:
I researched a lot but couldnt get the specific information
