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.

Inizia riproducendo la query where descritta nel connettore PostgreSQL e verifica come il filtro neq diventa SQL. Confronta la condizione != generata con il comportamento di NULL in PostgreSQL; il lavoro è completato quando le voci NULL vengono incluse come previsto, oppure quando la limitazione è documentata se tale comportamento non è supportato.
