I haven't seen this reported before. Are you sure Postgres deserves
the blame, rather than some other package? Postgres' use of shared
memory is fixed for the life of a postmaster, so unless you're
constantly restarting the postmaster I don't see how we could be leaking
shmem.
However, rather than speculate, let's get some hard facts. Try using
"ipcs -m -a" to keep track of shared mem allocations, and see what usage
is creeping up over time.
