• drop-invalid-dates comma,separated,date,fields input.csv output.csv converts date fields to Python dates, fields failing to convert are replaced with None/null
• generate-date-fixer R_export.txt.xls generate a script suitable for parallel --gnu that will create fixed rovat csvs when run

• rovat-to-psql rovat_n.csv rovat_n.fields helps loading rovat_n.csv properly into Postgres (uses csv_to_psql) creates table with correct field types and primary key on (ceg_id, alrovat_id)
