Don't agree. Getting managed postgress from one of the myriad providers is not much harder than using sqlite, but postgress is more flexible and future proof.
Why?
Because in 1999 when I started using PHP3 to write websites, I couldn't get MySQL to work properly and Postgres was harder but had better documentation.
It's ridiculous spinning up something as "industrial strength" as Postgres for a daft wee blog, just as ridiculous as using a 500bhp Scania V8 for your lawnmower.
Now if you'll excuse me, I have to go and spend ten seconds cutting my lawn.
