I haven't worked with them yet, but as I understand it FDW's (foreign data wrappers) present data from foreign sources (such as a CSV file) as a table inside the database. Once you have that, it should be fairly easy to craft an INSERT ... SELECT that converts the data on the fly. Or use an ETL tool - Pentaho is popular.
