manage raw where clause with array as param

[davidepaolotua]

Implements #1031

Btw, is there any reason for which the raw does param substitution and does not use bind variables? Albeit small, there might be a perf hit, in that case

oh awesome! You know, I'm not sure why the ? was used instead of bind variables... My only guess is because that's what Rails did? 🤷‍♂️ I know it has made a few of the jsonb operations a bit difficult.

I guess thinking about it.... If you did UserQuery.new.admin(true).where("something = ?", whatever) you'd have to know that the admin(true) is already using $1, so your ? would need to be $2 in this case. That could get real messy trying to track that in larger queries where you might use methods for a larger portion like

UserQuery.new.for_some_special_case.where("something = $5", whatever)

😂 I don't know if that's the real reason or not, but that's my best guess.
