--------------------------------

             Summary: Postgres of JDBC Connector enable case-sensitive.
                 Key: FLINK-23324
                 URL: https://issues.apache.org/jira/browse/FLINK-23324

          Components: Connectors / JDBC
    Affects Versions: 1.12.4, 1.13.1

Now the PostgresDialect is case-insensitive. I think this is a bug.

Could we delete PostgresDialect#quoteIdentifier, make it using super class.
