While I was trying to track down the cause of MADLIB-1068, I managed to put Postgres/MADlib under the debugger (gdb) and thought the configuration would be of some help to someone. Essentially, I built postgres with the following configure options:
configure --enable-cassert --enable-debug --with-python I then was able to start a psql session and attach to the running session with gdb. This allows one to set breakpoints, review variable values and all the other cool gdb debugging techniques. There is a reasonable amount of information one can find on using gdb and on the web. It was much easier than I originally envisioned. If anyone needs assistance with the setup, please don't hesitate to ping me. Happy MADilb Debugging, -=e -- *Ed Espino*
