According to the PostgreSQL help file EXECUTE is used to execute a
prepared statement. I tried that but when I call PREPARE with COPY as
the statement I get an error. Are you saying that I can also use EXECUTE as

EXECUTE AStringVariable;

where AStringVariable contains a valid SQL statement? If so, that is the
solution.
