Global snapshots
Check that global_snapshot_defer_time early instead of falling on assert. Also set default value to 30 secs. Mostly cosmetical improvements. * (Arguably) improved comments around locking during circular buffer maintenance; also, don't lock procarray during global_snapshot_xmin bump. * s/snaphot/snapshot, other typos. * Don't track_global_snapshots by default -- while handy for testing, it doesn't look generally good. (cherry picked from commit f9dd1c3) Fix initdb failure with non-zero global_snapshot_defer_time. And set its default value to 5. Also fix one warning (damned 'void' instead of true void). (cherry picked from commit d545692)
