 ## Upgrading from Spark SQL 3.1 to 3.2
 
+  - In Spark 3.2, PostgreSQL JDBC dialect uses StringType for MONEY and 
MONEY[] is not supported due to the JDBC driver for PostgreSQL can't handle 
those types properly. In Spark 3.1 or earlier, DoubleType and ArrayType of 
DoubleType are used respectively.
