gist_fast_build-0.9.1.patch.gz (application/x-gzip)

I found that in previous version of patch I missed PageSetLSN
and PageSetTLI, but huge amount of WAL is still here. Also I found that huge
amount of WAL appears only with -O2. With -O0 amount of WAL is ok, but
messages "FATAL:  xlog flush request BFF11148/809A600 is not satisfied ---
flushed only to 44/9C518750" appears. Seems that there is some totally wrong
use of WAL if even optimization level does matter...
