Sergey Nuyanzin commented on CALCITE-2754:
------------------------------------------

Yes, but based on article The New and Improved SQL:2016 Standard at 
https://sigmodrecord.org/2018/10/19/the-new-and-improved-sql2016-standard/
LISTAGG is a part of SQL 2016 Standard.

Or does it make sense to make LISTAGG as Oracle specific until SQL 2016 becomes 
public available?
