I wanted to keep the fcache code from doing anything not to do with caching, and I wanted to keep the permission check in the executor, like it is for tables. There were a couple of cases, which I have not fully explored yet, for which this seemed like a good idea, such as some functions being in the plan but not being executed, or the permission check being avoided for some functions (e.g., cast functions). -- Peter Eisentraut peter_e@gmx.net
