    ARRRRG - then next problem with VARSIZE - damn thing.

    This  time  it's during the parser (gdb told me). varcharin()
    is called with a atttypmod of  0  causing  a  palloc()  of  0
    bytes.  How should a VARCHAR type whithout a specified length
    behave? Is this type 1 character or a  variable  size  up  to
    4096?


Until later, Jan
