I read that as Uber discovered their code relied on MySQL default case insentivity. Migrating to Postgres might have been tricky as collation is a very recent addition in Postgres.
That could be. It was the "because the database just doesn’t respect case search" part that struck me -- to say that MySQL doesn't respect case search is false, and the only scenario I can think of where it can even appear to be the case is if you're new to MySQL and you've made a big assumption without even googling it. Or maybe if you're new to string comparison (and therefore programming?) in general.
