To test something unrelated, I set my shared_buffers to 7TB on my laptop today (no, unfortunately I don't have that much RAM).
That leads to the startup error: FATAL: -536870912 is outside the valid range for parameter "effective_cache_size" (-1 .. 2147483647) So clearly there is an overflow somewhere in the calculation of effective_cache_size, most likely from the fact that it's now dynamically calculated. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
