Hi,
I started working again on my
IDENTITY/GENERATED patch.
My question is $SUBJECT.
This code is in rewriteTargetlist():
new_attr = build_column_default()
new_tle = makeTargetEntry((Expr *) new_expr, ...)
Now, in ExecInsert() I have to compute
the default for IDENTITY/GENERATED
between ExecConstraints() and heap_insert().
How can I create a Datum out of either an Expr
or a TargetEntry (that contains the computed
constant out of the default expression) so I can
use it after I did an heap_deform_tuple()?
Best regards,
Zoltán Böszörményi
