  1. per backend WAL statistics 

    Now that commit 9aea73f added backend-level statistics to pgstats (and
per backend IO statistics) we can more easily add per backend statistics.

This commit adds per backend WAL statistics using the same layer as pg_stat_wal,
except that it is now possible to know how much WAL activity is happening in each
backend rather than an overall aggregate of all the activity.  A function called
pg_stat_get_backend_wal() is added to access this data depending on the
PID of a backend.

The same limitation as in 9aea73f persists, meaning that Auxiliary processes
are not included in this set of statistics.

XXX: bump catalog version
XXX: bump of stats file format not required, as backend stats do not
persist on disk.
