You will need to synthesize the complete query string yourself instead
of using a parameter placeholder, as it appears that the server doesn't
support a parameter placeholder as the filename argument to COPY FROM.
This is similar to how you can't use parameter placeholders for table
names, etc - the driver is limited by where the server's query parser
will accept a $1, $2, etc in the query string.

Though I'm not sure why the server doesn't allow this case, it seems
like the argument to COPY FROM is data, not structural. Perhaps the FROM
STDIN case is the problem.
