PostgreSQL version: 8.3
Operating system: Windows XP
Description: CSV feature request
Details:

Excel 2007 decides on the fly whether to quote fields or not on the basis of
whther individual rows have a comma in that field. There does not appear any
obvious way to prevent this bizarre behaviour.

I suggest the syntax:

COPY table (columns) FROM 'filename.csv. with csv OPTIONAL QUOTE [AS '"'];

As a way to tell PostgreSQL this behaviour is expected and must be handled
without complaint. Default should be to complain if file is stupidly
formatted.

Additionally, where a character that is not a member of the acceptable
character set is found, plese attempt to print it as char as well as
octal/hex. It can be very difficult to find which character is causeing the
problem! (Eg em-dashes, smart quotes)
