I am trying to override the NULL attributes in postgres to be a string instead of sql.NullString data type. I used every thing in configurations including override array in both version 1 and version2 of sqlc yaml files. Nothing is working and whenever I try to add the field emit_pointers_for_null_types, the console return "field emit_pointers_for_null_types not found in type config.v1PackageSettings" error message. I am using sqlc docker container laterst version 1.0.16 (but I tried to use v1.0.14, v1.0.4, v1.0.1 nothing is working)
