Reynold Xin updated SPARK-15229:
--------------------------------
Description:
Our case sensitivity support is different from what ANSI SQL standards support.
Postgres' behavior is that if an identifier is quoted, then it is treated as
case sensitive, otherwise it is folded to lower case. We will likely need to
revisit this in the future and change our behavior. For now, the safest change
to do for Spark 2.0 is to make the case sensitive option internal and
discourage users from turning it on, effectively making Spark always case
insensitive.
