Log Message:
-----------
fix: support insert ... on conflict...update for reWriteBatchedInserts=true (#1130)

pgjdbc will avoid rewriting the query if a bind is identified after values(...)

That is ON CONFLICT... DO update set x=? is NOT rewrite-compatible, and update set x='default' is rewrite-compatible
