Dylan Forciea updated FLINK-19771:
----------------------------------
Description:
When trying to utilize the JDBC Connector for Postgres, I tried to read in a
text array. When a row that was null was attempted to be read in, the connector
threw an exception and execution stopped. It appears looking at the source code
that if the row is null that it will still attempt to grab the contents out:
[https://github.com/apache/flink/blob/release-1.11.2/flink-connectors/flink-connector-jdbc/src/main/java/org/apache/flink/connector/jdbc/internal/converter/PostgresRowConverter.java#L97]
The stack trace is as follows:
{code:java}
