A good place to start is:

http://www.postgresql.org/docs/9.3/interactive/sql-copy.html

CSV Format

"....
The values in each record are separated by the DELIMITER character. If
the value contains the delimiter character, the QUOTE character, the
NULL string, a carriage return, or line feed character, then the whole
value is prefixed and suffixed by the QUOTE character, and any
occurrence within the value of a QUOTE character or the ESCAPE character
is preceded by the escape character. You can also use FORCE_QUOTE to
force quotes when outputting non-NULL values in specific columns. ..."

There is more, so I would read the whole section.
