Also reminds me that I really would like to find a way that PG can detect allocation failures without requiring memory overcommit to be turned off globally. Just causes too many other programs to misbehave, and is a complicated explicit configuration.https://twitter.com/AndresFreundTec/status/1225559052475871233 …

Perhaps we could make our stack-depth-checking function ensure that current_stack_depth + 1/10th max_stack_depth is backed by actual memory? Keeping a high watermark of how far we've guaranteed that, to avoid redundant syscalls?
