---------------------------------------
Summary: Upgrade postgresql to 42.4.1
Key: SPARK-39996
URL: https://issues.apache.org/jira/browse/SPARK-39996
Project: Spark
Issue Type: Dependency upgrade
Components: Build
Affects Versions: 3.4.0
Reporter: Bjørn Jørgensen
### Security
- fix: CVE-2022-31197 Fixes SQL generated in PgResultSet.refresh() to escape
column identifiers so as to prevent SQL injection.
- Previously, the column names for both key and data columns in the table
were copied as-is into the generated
SQL. This allowed a malicious table with column names that include statement
terminator to be parsed and
executed as multiple separate commands.
- Also adds a new test class ResultSetRefreshTest to verify this change.
