I'm sure there's been some bloat over time, but I can't offhand think of
a reason for it to be 10X more than 8.3 was.  You might try attaching to a
backend with gdb and doing "call MemoryContextStats(TopMemoryContext)"
periodically to try to identify where the memory is going.  (The output
from that will go to postmaster stderr, so make sure your logging
configuration will capture that.)
