pg_dump patch: Allow -X'exclude table from dump by pattern'

Ciao,
I had the need to exclude tables from the dump so I made this patch,
I do something like

pg_dump -X \"Test_*\" -X \"Devel*\" test

I'm not a C guru, but it work, the only thing I was unable to get rid
of is the dump of sequences for that table,

so I have to add -X tablename_id_seq

If you can suggest a way to work around it, I will try to fix it

hope it can be useful to the project

bye
