Re: [PR] [FLINK-35890][cdc] Select only the increment but still enter the SNAPSHOT lead to ckp failed [flink-cdc]

> Thanks @leosanqing for the contribution, could you also check other connectors? I think some start up mode of debezium should not pass to underlying debeziunm engine once the Flink CDC incremental snapshot mode enabled.
@leonardBang hi, sorry for so late to reply. I've test mysql and PG connector. PG can 100% reproduce, even though using master code version.
And because of Mysql use 2.0 chunk version by default, it avoids this bug. I use 1.0 Mysql version, can not 100% reproduce this bug, just reproduce once of 5 times.
I think mysql is not necessary to fix, because default is 2.0 chunk version. PG still use 1.0 version by default, should I commit another just fix PG-branch PR?
