Bob, the correct syntax is
update t3 set fld[1] = 0 where t3.fld[1] = 5 ;
UPDATE doesn't allow explicit specification of the table containing
a field to be updated; you have to write just the field name before the
"=". The parser's error message about that could stand improvement...
There are a whole bunch of bugs associated with arrays :-(, but this
behavior isn't one of them. I hope to get some time to clean up the
array code for 6.6 or 6.7.
