update db doesnt work - Mailing list pgsql-general

Hello,

i have created a table with 1600 comlumns. Now i want
to update some columns with new values:
update db set col1=1 where col2=2;

this generates the error-message:
heap_formtuple: numberOfAttributes of 1601 > 1600.


Any suggestions?

Thanks,

Dirk
