This commit enables the MCVs for text related types such as varchar, name etc to be passed to ORCA so that it can estimate the cardinalities for columns containing text related types. Prior to this commit, ORCA would estimate the cardinality to be 40% of the tuples which would cause mis-estimation for certain queries.
