I'm not sure what the question really is. Well, configure is used in
preparation for a full compile, so if you are going to touch only the
source code without having to change any external dependency, then you
don't need to run configure again (but you have to compile the tree of
course).
What is your aim?

Well, technically you could run 'make' (building the binaries) and
manually get that binary to wherever pg_ctl is looking...if you were
feeling really dirty you could use a symlink.  it's not clear how much
time you'd really be saving however -- the install step of make
doesn't really take all that long.  Also, there's no way to deploy
changes without restarting the server except in the very special case
of libraries loaded with LOAD.

Uhm...this is not OSGi. I don't believe it is possible to change such
a deep piece of code of the server without having to recompile (i.e.,
I don't think there is a dynamic linking available) and therefore
without having to restart the whole software.
