I'm not sure if this is worth documenting, but pg_dumping mixed-case tables with the '-t table' option appears to not be accurately documented for cmd.exe. Here are my four attempts, with only the last as success:

Intuitive (supplying "My Table" like "My Database"), but not correct:

C:\>"C:\Program Files\PostgreSQL\9.1\bin\pg_dump.exe" -U postgres -t "My Table" "My Database"

pg_dump: No matching tables were found

As documented in last example at http://www.postgresql.org/docs/9.1/static/app-pgdump.html

C:\>"C:\Program Files\PostgreSQL\9.1\bin\pg_dump.exe" -U postgres -t '\"My Table\"' "My Database"

pg_dump: too many command-line arguments (first is "My Database")
