Yeah. I'm not very happy with this line of development at all,
because I think we are painting ourselves into a corner by not allowing
code to detect whether a cancel is pending without having it happen
immediately. (That is, I do not believe that backend/regex/ is the
only code that will ever wish for that.) But if that is the direction
we're going to go in, we should probably revise these APIs to make them
less odd. I'm not sure why we'd keep the REG_CANCEL error code at all.

Meh ... CacheMemoryContext might not exist yet, especially for the
use-cases in the login logic.
