I heard about some bitrot creeping in here too, but it seems gone now; I 
had no problem merging Peter's development branch against master.  I've 
attached a newer patch of the main code, which fixes most of the earlier 
issues there were disclaimers about.  The two test programs from 
contrib/pg_stat_statements are attached as separate files for a cleaner 
diff.  Merged and rebased version now available from 
https://github.com/greg2ndQuadrant/postgres/tree/pg_stat_statements_norm 
too.
