   In DataFusion 43.0.0,   A portion of the TPCH query 7 execution plan looks 
like
   ```
   ProjectionExec: expr=[n_name@4 as supp_nation, n_name@0 as cust_nation, 
date_part(YEAR, l_shipdate@3) as l_year, l_extendedprice@1 * (Some(1),20,0 - 
l_discount@2) as volume], schema=[supp
   _nation:Utf8View;N, cust_nation:Utf8View;N, l_year:Float64;N, 
volume:Decimal128(38, 4);N]
   ```
   
   Whereas 44 produces:
   ```
   ProjectionExec: expr=[n_name@4 as supp_nation, n_name@0 as cust_nation, 
date_part(YEAR, l_shipdate@3) as l_year, l_extendedprice@1 * (Some(1),20,0 - 
l_discount@2) as volume], schema=[supp
   _nation:Utf8View;N, cust_nation:Utf8View;N, l_year:Int32;N, 
volume:Decimal128(38, 4);N]
   ```
   
   note the different schema value for `l_year`
