Heikki Linnakangas b9119f11bf Add perf test case for buffering GiST build. ...

When a WAL record affects multiple pages, we currently duplicate the
record for each affected page. That's a bit wasteful, but not too bad
for b-tree splits and non-hot heap updates that affect two pages. But
buffering GiST index build WAL-logs the whole relation in 32 page chunks,
with one giant WAL record for each 32-page chunk. Currently we duplicate
that giant record for each of the 32 pages, which is really wasteful.

Github issue https://github.com/zenithdb/zenith/issues/720 tracks the
problem. This commit adds a test case for it to demonstrate it.
