Feature request: include_tables parameter

[yannakopoulos]

I need to read data from a specific table present in many databases. Each database also includes an assortment of other tables that I don't want to read. The name of the table I would like to read is always the same, but the names of the other tables vary between databases. Instead of having to enumerate each unwanted table by name using the exclude_tables parameter, it would be useful to be able to specify which tables you would like included and ignore the rest using a hypothetical include_tables parameter.
