------------------------------------
[~qingru zhang] [~godfreyhe] Should we also add documentation for 1.14 and
1.13 ?

> Rowtime type is not correct for windowTableFunction or OverAggregate on Match

> changed from rowtime to rowtime_ltz in `RelTimeIndicator`.
> The bug could be reproduced by the following two cases:
