pgsql: Code review for dtrace probes added (so far) to 8.4. - Mailing list pgsql-committers

Log Message:
-----------
Code review for dtrace probes added (so far) to 8.4.  Adjust placement of
some bufmgr probes, take out redundant and memory-leak-inducing path arguments
to smgr__md__read__done and smgr__md__write__done, fix bogus attempt to
recalculate space used in sort__done, clean up formatting in places where
I'm not sure pgindent will do a nice job by itself.
