I prefer [-+][dtnf], which is similar to rsync --filter, and clear what it's
doing.  I wouldn't put much weight on what the short options are.

I wonder if some people would want to be able to use *long* or short options:

-table foo
+schema baz

Or maybe:

exclude-table=foo
schema=bar

Some tools use "long options without leading dashes" as their configuration
file format.  Examples: openvpn, mysql.  So that could be a good option.
OTOH, there's only a few "keys", so I'm not sure how many people would want to
repeat them, if there's enough to bother putting them in the file rather than
the cmdline.
