Hi i'm willingto help, if you could just point some places in code to get me started

@lukasz-bajor: Thanks for the offer. Pull requests are probably the best way to contribute in this case. However, there's a bit of work to do, in order to do this correctly / consistently. Fetching OUT parameters from a stored procedure should actually work in a similar way as fetching Result objects from a regular ResultQuery. This means that the ExecuteContext and ExecuteListener specs need to be adapted accordingly.

Note: This adapted listener behaviour might match the way Postgres deals with stored procedures and OUT parameters, which really produce rows, just like regular SELECT statements.

If you still want to try to tackle this problem, org.jooq.impl.AbstractRoutine is the place where you can start digging into the code. org.jooq.tools.LoggerListener is the type that does the current default logging.

This might be solved automatically by implementing #2640
