I also never heard it. In Brazil I only have heard SQL pronunced as sequel in NoSQL. SQLite is mostly pronounced S-Q-Light here, with the S and Q in Portuguese (weird, but it happens often)
Guilty as charged. Pronouncing letters and numbers in English requires an active mental effort for me, so that happens if I'm not paying attention. I guess it's because they don't really register as another language, even with context. My inner monologue also does letters and numbers in Portuguese, which doesn't help either.
