Description
Is your feature request related to a problem or challenge?
As discussed in #11207 The idea is to move hardcoded the sql_overlay_to_expr operator to function in the parser step, which is currently handled in the optimizer step. We need to implement user-defined parser mechanisms to enable more flexible SQL planning.
