Allow the wal_buffers setting to be auto-tuned to a reasonable value. If wal_buffers is initially set to -1 (which is now the default), it's replaced by 1/32nd of shared_buffers, with a minimum of 8 (the old default) and a maximum of the XLOG segment size. The allowed range for manual settings is still from 4 up to whatever will fit in shared memory.
