neq in where filter does not include null values

Description/Steps to reproduce

1. Create a model with String properties
2. Insert instances with one of the string properties unset. (NULL in DB)
3. Run a query for model {where: {stringProp: {neq: "value"}}}
4. NULL entries are not included

Expected result

Null entries are not equal to value so should be included

Additional information

I notice that the output sql from the connector is !=, whereas IS DISTINCT FROM would work for NULL values. As far as I can tell, there is no operator that will invoke IS DISTINCT FROM. If this won't be fixed/is considered not an issue, having this at least documented somewhere would be useful.

Empieza reproduciendo la consulta where descrita en el conector de PostgreSQL e inspecciona cómo el filtro neq se convierte en SQL. Compara la condición != generada con el comportamiento de NULL de PostgreSQL; se considera terminada cuando las entradas NULL se incluyen como se espera, o cuando se documenta la limitación si ese comportamiento no es compatible.
