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.
