With best regards,
Alexander Korotkov.
I checked out master and put together a test case using a small percentage of production data for a known problem we have with Pg 9.2 and text search scans.A small percentage in this case means 10 million records randomly selected; has a few billion records.Tests ran for master successfully and I recorded timings.
Applied the patch included here to master along with gin-packed-postinglists-14.patch.Run make clean; ./configure; make; make install.make check (All 141 tests passed.)initdb, import dump
The GIN index fails to build with a segfault.
Thanks for testing. See fixed version in thread about packed posting lists.
