Fix analyze for array type columns 

`hashDatum` expects the incoming oid for the array types to be
ANYARRAYOID, else it will flag them as unsupported.  While performing
the MCV calcuation on the array type columns, we were passing the
specific array oid, i.e character array oid for char array type column,
due to which `hashdatum` was marking them as not supported.  However, we
should pass ANYARRAYOID if the column is an array type. This commit
fixes the issue.

Also, relevant test cases are added.
