It creates a new child process.  Read
http://www.postgresql.org/docs/devel/static/overview.html
particularly section 48.2.

It sounds like you're setting breakpoints in the postmaster process,
which will never be hit.  Attach to the relevant backend process instead.
(Select pg_backend_pid() in your client if you're not sure which that is,
or you can discover it from "ps auxww" output.)
