Revert sampling patch for EXPLAIN ANALYZE; it turns out to be too unreliable
...
because node timing is much less predictable than the patch expects. I kept
the API change for InstrStopNode, however.

Code review for EXPLAIN patch. Fix some typos, make it behave sanely
...
across multiple loops, get rid of the shaky assumption that exactly one
tuple is returned per node iteration.

Create a new 'MultiExecProcNode' call API for plan nodes that don't
...
return just a single tuple at a time. Currently the only such node
type is Hash, but I expect we will soon have indexscans that can return
tuple bitmaps. A side benefit is that EXPLAIN ANALYZE now shows the
correct tuple count for a Hash node.

Improve EXPLAIN ANALYZE to show the time spent in each trigger when
...
executing a statement that fires triggers. Formerly this time was
included in "Total runtime" but not otherwise accounted for.
As a side benefit, we avoid re-opening relations when firing non-deferred
AFTER triggers, because the trigger code can re-use the main executor's
ResultRelInfo data structure.
