What is the official pronunciation for "SQLite"?

It's S-Q-L-ite, like we pronounce kryptonite.

I don't know about SQLite, but I started out pronouncing "ess-cue-ell" until I figured out that "SEE-quell" is a much smoother interpretation of "SQL". So, personally I would say "SEE-quell-light", despite my family's preponderance of geologists.

Now, let's do "PostgreSQL"!
