But just to clarify further, that only works with sql. Copy needs the '\'
approach.
So many choices ;-)

Copy doesn't need it at all, because you don't have quotes around the
fields. The following is from my 6.4.2:

testing=> \d test

Table    = test
+-----------------------------+-----------------------------+-------+
|              Field          |              Type           | Length|
+-----------------------------+-----------------------------+-------+
| t                           | text                        |   var |
+-----------------------------+-----------------------------+-------+
testing=> copy test from stdin;
Enter info followed by a newline
End with a backslash and a period on a line by itself.

testing=> select * from test;

This is a field without a quote.
Here the word 'field' is in quotes.
Isn't it nice to have one quote in this field?
(3 rows)

I hope this convinces you...
