Does that code cause the variables value to change from function call to function call (what most users would expect if they give it a default value based on a call argument), or will remember the value from the first function call for the lifetime of the backend?
I believe it will evaluate the DEFAULT expression on each entry to the block, using the current values of outer-block variables (and also variables declared earlier in the same block, if anyone cared to use that behavior). The code was already designed and documented to evaluate DEFAULT expressions on each block entry --- what it was missing was the ability to reference variables in these expressions.
Do you see something wrong with it?
No, I just didn't test it yet. My only concern was that it could be another unexpected behaviour related to caching values/plans. Unexpected caching is what most likely becomes FAQ's and I think we have enough of those.
