If we want to expose that level of detail, I think either JSON or arrays
would make more sense, so we're not stuck with a limited amount of info.
Perhaps DDL would be OK with the numbers you suggested, but
https://www.pgcon.org/2013/schedule/events/576.en.html would not, and I
think wanting query progress is much more common.
You need to restrict the amount of info, because you've got to
preallocate enough shared memory to store all the data that somebody
might report.
I was thinking your DSM stuff would come into play here. We wouldn't
want to be reallocating during execution, but I'd expect we would know
during setup how much memory we actually needed.
