Even if there were, it seems unlikely that we could reallocate shared memory without stopping all active transactions, so it'd be barely less invasive than a postmaster restart anyhow.
What about allowing shared_buffers to be only greater than it was at server start and allocating the extra shared_buffers in one or more additional shm segments?
