 8) Can I use DTrace for tracing PostgreSQL?
 
-PostgreSQL 8.2 has implemented DTrace support.  You can enable it by
-the --enable-dtrace configure switch.  If you want to build 64-bit
-binaries with DTrace you must specify DTRACEFLAGS='-64', e.g.,
-
-Using GCC compiler:
-
-       $ ./configure CC='gcc -m64' --enable-dtrace DTRACEFLAGS='-64' ...
-            
-Using Sun compiler:
-
-       $ ./configure CC='/opt/SUNWspro/bin/cc -xtarget=native64' --enable-dtrace DTRACEFLAGS='-64'
-
+Yes, see the chapter "Monitoring Database Activity" in the documentation
+for further information.
