For what it's worth, I understood the comment the way it was intended in the first place. SQLite is an example of a high-quality codebase, and is available on multiple platforms. He could just as well have said "what, like SQLite, postgresql, and numerous other projects?".
The keyword here is "What", which you conveniently left out of the quote. It demonstrates the author's confusion.
Having said that, (written) language is a very error prone method of communication, even more so on an internet forum .
Unfortunately, the grandparent forgot that Sarcasm Does Not Work On The Net (old timers would recognize the SDNWOTN acronym. It really should be known better).
Back in '94, most sarcastic posts would get this reply as a first reply, which also served as a hint to other readers whose sarcasm detector failed to be triggered.
Yes, the Interwebs make it difficult to spot sarcasm, but another thing people need to realize is that some cultures don't have sarcasm to the same extent as in Western countries (UK, US, Canada).
