Selectively Compile psql

I guess this question will be too easy to most of the people here,
though I couldn't figure this out myself. I want to recompile only psql
with the readline library. When I installed PG, GNU readline package was
not there. Now db is running fine, and I don't want to disturb it. Can
anybody point me to the brief steps to do this.

There is not presently any method to recompile only psql. However, you
could reinstall only psql. Try this:

cd ...postgres top directory...
./configure same-options-as-you-used-before
make
cd src/bin/psql
make install
