Thanks for getting these committed!

I rebased the custom callbacks patch in v5.

One very minor thing from the earlier commits that I corrected here is
the test for entry 2 after a clean restart.

-is($result, "entry1|2", "variable-sized stats persist after clean restart");
+is($result, "entry1|2|Test entry 1", "variable-sized stats persist
after clean restart");
+
+$result = $node->safe_psql('postgres', q(select * from
test_custom_stats_var_report('entry2')));
+is($result, "entry2|3|Test entry 2", "variable-sized stats persist
after clean restart");
