Display total time and I/O timings in milliseconds, for consistency with the units used for timings in the core statistics views. The columns remain of float8 type, so that sub-msec precision is available. (At some point we will probably want to convert the core views to use float8 type for the same reason, but this patch does not touch that issue.) This is a release-note-requiring change in the meaning of the total_time column. The I/O timing columns are new as of 9.2, so there is no compatibility impact from redefining them. Do some minor copy-editing in the documentation, too.
