I found it difficult to apply 'SET datestyle' within the same session when applying the psql command. Altering the datestyle on the whole database/server (just for the import) also might cause side effects on other users or existing applications. So i usually modify the file itself before loading:

#!/bin/bash 
#
# change from dd.mm.yyyy to yyyy-mm-dd inside the file
# note: regex searches for date columns separated by semicolon (;) 
sed -i 's/;\([0-9][0-9]\)\.\([0-9][0-9]\)\.\([0-9][0-9][0-9][0-9]\);/;\3-\2-\1;/g' myfile
# then import file with date column
psql  -c "\COPY mytable FROM 'myfile' ...."
