Re: Question about weird COPY syntax

While asking questions about the grammar of COPY why do we have a
bracket of `[ [ WITH ] ...` rather than `[ WITH ]` ...

COPY tablename [ ( column [, ...] ) ]
        FROM { 'filename' | STDIN }
        [ [ WITH ]   (why is this opening bracket that is never closed here.)
                        [ BINARY ]
                        [ OIDS ]
                        [ DELIMITER [ AS ] 'delimiter' ]
                        [ NULL [ AS ] 'null string' ]
                        [ -PERL_key = value ]
                        [ -PERL_key ]
                        [ CSV [ HEADER ]
                                [ QUOTE [ AS ] 'quote' ]
                                [ ESCAPE [ AS ] 'escape' ]
                                [ FORCE NOT NULL column [, ...] ]
                                [ -TCSV_key ]
                                [ -TCSV_key = value ]
