moniker_map
Overrides the default table name to moniker translation. ...
The default behavior is to split on case transition and non-alphanumeric

Table Name | Moniker Name
---------------------------------
luser | Luser
Using dbicdump, perhaps:
dbicdump -o dump_directory=./loader -o moniker_map='{round=>"Round",rounds=>"Rounds"}' Tennis::Schema dbi:Pg:dbname=tennis002 '' ''
