Tom Lane e524cbdc45 Track typmods in plpgsql expression evaluation and assignment. ... The main value of this change is to avoid expensive I/O conversions when assigning to a variable that has a typmod specification, if the value to be assigned is already known to have the right typmod. This is particularly valuable for arrays with typmod specifications; formerly, in an assignment to an array element the entire array would invariably get put through double I/O conversion to check the typmod, to absolutely no purpose since we'd already properly coerced the new element value. Extracted from my "expanded arrays" patch; this seems worth committing separately, whatever becomes of that patch, since it's really an independent issue. As long as we're changing the function signatures, take the opportunity to rationalize the argument lists of exec_assign_value, exec_cast_value, and exec_simple_cast_value; that is, put the arguments into a saner order, and get rid of the bizarre choice to pass exec_assign_value's isNull flag by reference.		11 years ago
