An attached patch implements this. The problem with implementing this is
that the new syntax is:
.... WITH DELIMITERS '<delim>' WITH NULL AS '<char>'
Naturally, this leads to a shift/reduce conflict. Solution is more or less
that used with CREATE DATABASE WITH ... WITH ... etc. The only ugly bit
was mixing this with the old USING DELIMITERS ... syntax. I don't like the
solution -- I get the feeling there's a better way to do it.
The other option of course is to update yylex() to create a new token
in the same way that the UNIONJOIN terminal is created. But I think this
is a bit messy.
Ideas or is this okay?
