Mingliang Liu created FLINK-29750:
-------------------------------------

             Summary: Improve PostgresCatalog#listTables() by reusing resources
                 Key: FLINK-29750
                 URL: https://issues.apache.org/jira/browse/FLINK-29750
             Project: Flink
          Issue Type: Bug
          Components: Connectors / JDBC, Table SQL / Ecosystem
            Reporter: Mingliang Liu


Currently the {{PostgresCatalog#listTables()}} creates a new connection and prepared statement for every schema and table when listing tables. This can be optimized by reusing those resources.
