Committed with a couple of changes:

* I changed the function name from pg_stat_snapshot_timestamp to
pg_stat_get_snapshot_timestamp, which seemed to me to be the style
in general use in the stats stuff for inquiry functions.

* The function should be marked stable not volatile, since its value
doesn't change any faster than all the other stats inquiry functions.
