@alamb I found a bug concerning TIMESTAMP. I'll create a fix for that.

For today, I'll not add anything, possibly tomorrow. Maybe we can have a hotfix for now?

Beautiful -- thank you @AugustoFKL

@AugustoFKL can you please resolve the conflicts in this PR and then I will merge it? Thank you

Done! @alamb please LMK if I should follow another pattern, but I usually rebase and force-update the PRs.

Is that ok?

Thanks! In general when reviewing PRs I find it easier to review merges rather than rebases (as then it is clear what has changed since I last reviewed). For small PRs like this one, it is fine though -- no worries

[alamb]

Thanks again @AugustoFKL

What do you mean by "hotfix" -- would you like me to release a new version of sqlparser-rs?

Would it be possible, like, in the next week? I mean, if possible of course. Sorry if it looked like I was rushing or something like that

Sure -- no problem -- the releases are fairly small overhead these days. I'll get it done over the next day or two

I released version 0.25.0: https://crates.io/crates/sqlparser/0.25.0
