What are some valuable database certifications?

Hi, I have a love for relational database systems and I've been self teaching myself as much as I can about administrating them and getting more proficient in SQL. My goto database is PostgreSQL.

I was wondering if there are some valuable certifications I could get to make my experience more 'official'.

Are certifications usually considered / important when hiring for positions? Is this goal worth the time overall?

I feel like lately I never see positions list database experience per se, just 'needs X language'.

Thanks, any discussion is highly appreciated.
