What are the minimal files required to backup a postgresql database

I need to package the ability to backup a PostgreSQL database in my application?

I obviously need to add pg_dump.exe to the package, and the dlls
required are listed below,

15/08/2007 15:41 12,288 comerr32.dll
15/08/2007 15:41 139,264 gssapi32.dll
15/08/2007 15:41 19,968 k5sprt32.dll
15/08/2007 15:41 602,112 krb5_32.dll
27/02/2007 15:39 1,040,384 libeay32.dll
31/01/2003 19:41 916,849 libiconv-2.dll
16/03/2004 16:37 898,048 libiconv2.dll
27/04/2004 10:45 32,256 libintl-2.dll
06/05/2005 17:52 103,424 libintl3.dll
31/10/2008 07:15 167,936 libpq.dll
05/11/2005 14:51 169,092 libpq81.dll
16/10/2007 13:40 348,160 msvcr71.dll
02/12/2006 00:03 626,688 msvcr80.dll
09/03/2010 16:09 520,190 sqlite3.dll
27/02/2007 15:40 196,608 ssleay32.dll

Are there any other executables besides pg_dump I need to add to this list?

If some of them are likely to come in useful, rather than necessary
for backup I don't mind adding them
