* [PATCH 2/8] Write WAL for empty nbtree index build

After relation truncation indexes are also rebuild. It doesn't emit
WAL in minimal mode and if truncation happened within its creation
transaction, crash recovery leaves an empty index heap, which is
considered broken. This patch forces to emit WAL when an index_build
turns into empty nbtree index.

Is the message useful for pgbench users? I saw the error is ignored
in pg_dump, for example in bin/pg_dump/parallel.c
/*
* Send QueryCancel to leader connection, if enabled. Ignore errors,
* there's not much we can do about them anyway.
*/
if (signal_info.myAH != NULL && signal_info.myAH->connCancel != NULL)
(void) PQcancel(signal_info.myAH->connCancel,
errbuf, sizeof(errbuf));

I think the situation is different from pg_dump. Unlike pg_dump, if
PQcancel does not work, users can fix the problem by using
pg_terminate_backend or kill command. In order to make this work, an
appropriate error message is essential.

Makes sense. I fixed to emit an error message when PQcancel fails.
Also, I added some comments about the signal handling on Windows
to explain why the different way than non-Windows is required;
+ * On Windows, a callback function is set in which query cancel requests
+ * are sent to all benchmark queries running in the backend. This is
+ * required because all threads running queries continue to run without
+ * interrupted even when the signal is received.
+ *
Attached is the updated patch, v6.
