Subject: How to do the modular test

Hi pgsql-hackers,

Could anyone advise me how to do modular test in any partial
PostgreSQL's modules?
I am interested in the PostgreSQL development. I have begun study the
DBMS source code by developer documentation provided by postgresql.org
especially internal.ps that is the best explaination for developer
beginner, I think.
Moreover, the RedHat SourceNavigator I have found, is a great tools for
me. Without it, I might not able to get more understanding of the
PostgreSQL source code.
Now I am concentrating on the Executor module. I plan to create a new
Join Executor let's say ParallelJoin to enhance the Join operator
processing. As this moment, I may use the HybridJoin algorithm
implementing in the HashJoin module as my guidance but the NestLoop and
MergeJoin may be considered in the furture.

What I would like to know is, if I have changed some ot the modules,
how can I use GNU gdb to debug the modified codes?

I am sorry if the question is disturb your mailing list. I know this is
not the issue related in your TODO list. However I have expected to your
response.

thanks and regards,
Werachart.
