Hans,
You are right about the startup memory - here is the top line for a few
seconds after startup :
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
10116 postgres 15 0 3816 3816 3180 R 33.8 1.0 0:01.03 postmaster
seems that VIRT, RES, SHR all get the increase counted against them as
time goes on (as Tom suggested, I guess its to do with how top does its
accounting on this platform).
