Re: foreign key on virtual generated column

Hi Jian,

did initial testing and review ,the patches LGTM except
indentation we can solve this by running pg_indent.

i have one doubt that why we are using compute_virtual
argument todo the same work in both cases, is it because
of future proofing ,like we may do something different for
stored and virtual in future?

/* No luck, so prepare the expression for execution */
if (attgenerated == ATTRIBUTE_GENERATED_STORED)
{
ri_GeneratedExprs[i] = ExecPrepareExpr(expr, estate);
ri_NumGeneratedNeeded++;
}
else if (compute_virtual)
{
ri_GeneratedExprs[i] = ExecPrepareExpr(expr, estate);
ri_NumGeneratedNeeded++;
}
