    I agree. It only makes sense when we use it in SELECT statement. However, 
our parser allows `quoted Identifiers (using backticks)` in any part of the SQL 
statement. Below is the just the example. If we turn on this conf flag, will it 
cause the problem for the other users when they have quoted identifiers in the 
query except Project/SELECT list?
