We think this
ctxparameter might have been added a few months ago as part of some optimization work which never made it across the line. Instead of threading a*sql.Contexteverywhere, if we have need of a*sql.Contextduring analysis or to precompute or materialize a certain result in the future, I think I'm going to advocate for a specific optional interface that the analyzer is aware of. It could then pass the context through at a specific analyzer phase and the function/expression node would have the opportunity to get ready to do what it needs to.
