[Fix][Connector-jdbc] Fix postgresql sink trying to update unique key (#9293)

[papadave66]

Purpose of this pull request

close #9293

The JDBC connector of postgresql trying to update primary key colums which is not needed. Then I do some research on apache/flink-connector-jdbc#155 . They fix this month ago. So I think fix in here should be a good idea :)
And I use [fix] instead of [bug] because I am not sure if it is a bug or a feature.

Does this PR introduce any user-facing change?

No
