Andrew Pilloud commented on BEAM-9698:
--------------------------------------
The LogicalProject is produced by `ArrayScanLiteralToUncollectConverter` The
input from the parser:
```
ArrayScan
+-column_list=[$array.$unnest1#1]
+-array_expr=
| +-Literal(type=ARRAY<INT64>, value=NULL, has_explicit_type=TRUE)
+-element_column=$array.$unnest1#1
```
It appears the cast doesn't make it out of the parser.
