There are quite a few crash recovery tests that one of our QA persons
(Dharmendra Goyal) has written. I can post them if necessary. We run
these tests very regularly.

Apart from these regression crash tests, I had mostly tested by
running lot of concurrent clients on UP/SMP machines, crashing
and recovering the database. We fixed quite a few issues with
these tests. I have tried crashing in middle of UPDATEs/INSERTs/DELETEs

I know Heikki changed that when he did the initial refactoring, but not
sure why. May be he wanted to make it more consistent.
But I don't think its broken because we collect the offsets in one-based
format in PageRepairFragmentation, WAL log in that format and redo
the same way. Am I missing something ?
