Looking at the pgsql-committers message is the easiest way to verify
which files were touched:
http://archives.postgresql.org/pgsql-committers/2005-11/msg00307.php
It also provides links that will give you the per-file diffs directly.
In this case, since the patch touches the widely known EState struct,
I'd recommend a full backend recompile after patching.
