Could you introduce a hack creating deterministic server side crashes in order to test this out? The simplest thing that comes to mind is a rule like "kick shared memory in the teeth to force a crash after every 100 commits", then see if #100 shows up as expected. Pick two different small numbers for the interval and you could probably put that on both sides to simulate all sorts of badness. -- Greg Smith 2ndQuadrant US greg@2ndQuadrant.com Baltimore, MD PostgreSQL Training, Services, and 24x7 Support www.2ndQuadrant.us "PostgreSQL 9.0 High Performance": http://www.2ndQuadrant.com/books
