Hello, For future reference, this issue was also reported here on GitHub: https://github.com/jOOQ/jOOQ/issues/6797
I'm generally wary of setting the collation to something non-default on a connection / database level. I've only ever found this feature useful on an individual column level. In principle, 'A' != 'a' for most purposes (e.g. comparing two hashes), and only in some very few cases, I'd like this sort of case insensitive behaviour to work automatically, and even then, I generally prefer a programmatic workaround (e.g. creating a function based index on UPPER(column) or some other normalisation function, if UPPER() doesn't behave correctly in all languages). I'm not sure about a workaround here - have you considered asking this question on Stack Overflow (and perhaps reducing your API usage to JDBC only, to get more people to look into this)?
