I am sorry, maybe I should make my question clearer, I only want to know,
in 8.4.0 or newer version,
 whether I can debug posgres in the bare backend mode (in  usingddd-postgres
<http://www-inst.eecs.berkeley.edu/~cs186/fa04/usingddd.pdf>, he said that "
There are two ways to debug postgres (a) in the interactive mode and (b) in
the bare backend mode"
), if yes, what should I do?  thanks in advance!
