Description

We want to add the alias to_varchar for the function to_char. 

For users who are migrating to Spark SQL such that the SQL engine they formerly used supported to_varchar instead of to_char, this change would minimize the number of changes to their application to ensure it is compatible with Spark SQL syntax and support.
