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
(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'.
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.
