(2) Use a course enough granularity on time and a short enough maximum for the GUC to just keep a circular buffer of the mappings in memory. We might be able to make this dense enough that one minute resolution for up to 60 days could fit in 338kB. Obviously that could be reduced with courser granularity or a shorter maximum.
This doesn't sound too bad to me. Presumably these would be tunable. I think one minute granularity would be fine for most purposes, but I can imagine people who would want it finer, like 10 seconds, say.
