Something like that, yes. More info at https://english.stackexchange.com/questions/431329/what-is-the-correct-pronunciation-of-sqlite with links to videos of Richard Hipp (creator of SQLite) pronouncing it.
I actually couldn’t find a section on pronunciation in the official FAQ, though I think it was there in the past. Still, they do use phrases such as “an SQLite database”, indicating that “SQLite” starts with a vowel sound.
Hmm. According to Wikipedia you are correct, and the original SEQUEL was simply renamed to SQL. https://en.wikipedia.org/wiki/SQL#History
I’m not sure how much that original SEQUEL/SQL has in common with later publicly-available SQL implementations. I never personally worked with SEQUEL but I was under the impression it was more of a spiritual predecessor to SQL than a direct ancestor. But I trust Wikipedia more than I trust my my memory here, so I guess I was wrong.
