It would be nice if there were some way for extensions to declare GUC lists (the very thing that recently became explicitly unsupported). The difficulty seems to be that a GUC may be assigned before the extension has been loaded to determine whether list syntax should apply. Could a change like this improve that situation too, perhaps by deciding that += syntax /implies/ that an as-yet-undeclared GUC is to be of list form (which could then be checked when the extension declares the GUC)? -Chap
