psql /copy is MUCH faster than psycopg2 copy_expert()

Inserting a 50mb CSV file took all of 2 seconds for psql /copy and 215 seconds for psycopg2 copy_expert - 100x faster, 2 orders of magnitude faster on the same machine!

We're calling several CLI commands already - qsv, iconv, file & uchardet - might as well add psql to the mix.
