Hmm. While reading through the patch, I am wondering if this approach
to this kind of problem is the right thing to do long-term, relying on
a static flag to decide if the nesting level should be manipulated or
not when we end the executor. pgss is not the only module where I
have seen that we want to track a nesting level in a precise way. So
could be it more flexible to attach that to a backend structure at
this point and make manipulations of this number through the core
backend, reducing TRY/CATCH blocks required in extension code?
