I would prefer to drop the PG_ prefixes on PG_TRACE and pg_trace.h.  We 
know which software we're dealing with.

We should probably move the probes file to a subdirectory.  Anyone know 
a good place?

Also, again, the pgsql prefix should be dropped.

Certainly doable, but will that be more reliable?  Can't we convince 
dtrace to create binaries for the host platform by default?

I'm working on renaming the dependency files.
