Hi. I have problems on how to debug PostgreSQL on Linux using GDB. I made some changes to src/backend/utils/sort/tuplesort.c but it hangs while performing run formation (where my changes are).
I configured it using ./configure --prefix="/usr/local/pgsql/8.3/" CFLAGS="-O0 -DTRACE_SORT" --enable-debug --enable-cassert --enable-depend and trying to debug it using 'gdb postmaster' (which revealed to be not a very good idea) and 'gdb pg_ctl' followed by 'run -D /usr/local/psql/data' This last choice allowed me to set a breackpoint on puttuple_common (contained into tuplesort.c) but then I'm unable to run 'psql'. http://pastebin.com/m6a97b4dd I'm new on GDB and it's also my first postgrest patch. I just want some suggestion to know if I'm on the right way or not. Thanks for your time. PS: I suppose I'll write some related "HowTo Debug PostgreSQL with GDB - Basics" for newbies like me.
