Clarify pg_dump documentation
Clarify in the help output and documentation that -n, -t etc. take a "pattern" rather than a "schema" or "table" etc. This was especially confusing now that the new pg_dumpall --exclude-database option was documented with "pattern" and the others not, even though they all behave the same.
