Applying a patch is not a task that is in any way specific to
PostgreSQL, so it doesn't, I think, belong in PostgreSQL's manual.

A patch is produced by using "diff -c" or "diff -u"; it contains file
pathnames like this:

The patch is applied with the command "patch" - check its man page.

If your current directory is postgresql-7.2.1, you will apply the above
patch with the command "patch -p1 </path/to/the/patch/file"; "-p1" tells
patch to drop one path element from the pathname of the files to be
patched; in this example, that would change the first path to
"contrib/rserv/Makefile".  If there is no path element to drop, use
"-p0".
