\copy and identifier quoting

Isn't this a bug?

regression=# create table FOO (f1 int);
CREATE TABLE
regression=# \copy FOO from stdin
ERROR:  Relation "FOO" does not exist
\copy: ERROR:  Relation "FOO" does not exist
regression=#

This happens because \copy takes the given table name and slaps
double quotes around it, so the backend gets COPY "FOO" ...
rather than COPY FOO ...

It seems to me that psql's \copy should interpret the table name
the same way that a regular SQL command would: honor double quotes,
downcase in the absence of quotes.

Comments, objections?

Yes, that makes perfect sense.
