The attached patch (against HEAD) implements
COPY x (a,d,c,b) from stdin; COPY x (a,c) to stdout; as well as the corresponding changes to pg_dump to use the new functionality. This functionality is not available when using the BINARY option. If a column is not specified in the COPY FROM statement, its default values will be used. In addition to this functionality, I tweaked a couple of the error messages emitted by the new COPY <options> checks. Brent Verner
