Are you aware that Postgres 7.2 has been released in 2002? It is EOL (end-of-life) since 2005 by looking at the release notes.
I know the released time.

If you are planning to do some development in the future with or for Postgres, you would get a better insight by looking at more recent code. Here are some guidelines for example to use git, which is really helpful as a base infrastructure when studying the code: https://wiki.postgresql.org/wiki/Working_with_GIT
seemly the wiki you said has no information about debug
I am sorry, maybe I should make my question clearer, I only want to know, in 8.4.0 or newer version,
whether I can debug posgres in the bare backend mode (in usingddd-postgres, he said that "
There are two ways to debug postgres (a) in the interactive mode and (b) in the bare backend mode"
