Works for me. You sure that the pg_dump is actually 8.4? The -t switch
wasn't bright enough to understand wildcards before 8.2.
Another possibility is that the schema isn't really named myschema
(case sensitivity issues there).

Check out pg_dump's documentation (Joshua has already posted the link) Thomas

pg_dump's wildcard is * though.
