Re: BUG #17195: Can't bind $1::int param when I use COPY TO STDOUT statement - libpq, C++ - Mailing list pgsql-bugs

Don't hold your breath for that to work :-(.  Utility statements in
general do not support parameterization.  COPY is not an exception,
even when it contains what looks like a full DML command.  Maybe
somebody will improve that someday, but we'll certainly treat it
as a new feature not a bug fix.
