Change pg_stat_all_tables and sister views to put the recently-added
vacuum/analyze timestamp columns at the end, rather than at a random spot in the middle as in the original patch. This was deemed more usable as well as less likely to break existing application code. initdb forced accordingly. In passing, remove former kluge for initializing pg_stat_file()'s pg_proc entry --- bootstrap mode was fixed recently so that this can be done without any hacks, but I overlooked this usage.
