My €0,02: rename the dimensions to vl_len_ to avoid confusion and get
compiler errors where you now use 'dimension'. Add a macro that converts
a pointnd structure to dimension int by taking the VARSIZE_ANY_EXHDR /
sizeof(float8) and use it where dimension is used now. Or if your
database is small you could keep dimension in the structure.
