Hi hackers,
When reading the code, I found that in function CommandIsReadOnly[1], "select
for update/share" is defined as "not read only".
[1]-----------------
if (pstmt->rowMarks != NIL)
return false; /* SELECT FOR [KEY] UPDATE/SHARE */
-----------------
And from the comment [2], I think it means we need to CCI for "select for
update/share ",
I am not very familiar this, is there some reason that we have to do CCI for
"select for update/share " ?
Or Did I misunderstand ?
[2]-----------------
* the query must be *in truth* read-only, because the caller wishes
* not to do CommandCounterIncrement for it.
-----------------
Best regards,
