The docs for a contrib package are in their directory. For PostgreSQL
7.4.6, the readme file for the contrib package is here:
postgresql-7.4.6/contrib/dblink/README.dblink
and the docs are int the directory
postgresql-7.4.6/contrib/dblink/doc
Assuming you have the .tar.gz version of postgresql. IF you install
postgresql via packages then the location of such files are dependent on
how your packages are installed by your distribution.
