You should look at the gdb documentation, but running a standalone
backend under gdb isn't hard:
gdb path-to-postgres-executable
gdb> break elog
gdb> run command-line-arguments-for-standalone-backend
...
... break at elog
...
gdb> bt (backtrace)
gdb> cont (continue till next breakpoint)

Not sure, but I doubt it. If you don't see a symbolic backtrace
including routine names and argument values, then you haven't got
debugging symbols. In particular, if you can't see the string
being passed to elog then you'll have trouble telling which breakpoint
stop is the interesting one ...
