It looks like this patch set needs a bit of surgery to adapt to the LLVM
changes in 9dce22033d. The cfbot is reporting compiler warnings about
this, and also some crashes, which might also be caused by this.
I do like the updated APIs. (Maybe the repeated ".DebugPrint = NULL,
/* default message is fine */" lines could be omitted?)
I like that one can now easily change the elog(WARNING) in
ResourceOwnerReleaseAll() to a PANIC or something to get automatic
verification during testing. I wonder if we should make this the
default if assertions are on? This would need some adjustments to
src/test/modules/test_resowner because it would then fail.
