I added this:

/*
* We use the hopefully-safely-small value of 100kB as the compiled-in
* default for max_stack_depth. InitializeGUCOptions will increase it if
* possible, depending on the actual platform-specific stack limit.
*/

although I don't entirely see the point. We are certainly not going to
comment every variable whose compiled-in default gets changed by later
processing.
