I considered putting it in src/bin/scripts where reindexdb and vacuumdb also live.  It seems most similar to those two tools.

But if we ever get to that, this program should be the prime example why the current organization is problematic, and we should be prepared to make the necessary moves then.

Before settling on contrib/pg_amcheck as the location, I checked whether any tools under src/bin had dependencies on a contrib module, and couldn't find any current examples.  (There seems to have been one in the past, though I forget which that was at the moment.)

I have no argument with changing the location of this tool before it gets committed, but I wonder if we should do that now, or wait until some future time when contrib gets reorganized?  I can't quite tell which you prefer from your comments above.
