Support many-to-many via array column instead of via a join table

I am trying to generate the following sql with linq but no success so far:

SELECT
    t1.id,
    t2.id
FROM public.table1 t1
INNER JOIN public.table2 t2 ON ARRAY[t2.id]::bigint[] <@ t1.t2_ids;

Table1:

public class Table1
{
    public long Id { get;set; }
    public long[] T2Ids { get; set }
}

Table2:

public class Table2
{
    public long Id { get;set; }
}

Is this possible with LINQ?

This is definitely not something that EF Core can generate at this point.

Note https://github.com/dotnet/efcore/issues/23523 which is about providing this for Cosmos (some info also in https://github.com/dotnet/efcore/issues/16920#issuecomment-989721078); the same work could be done for PostgreSQL as well. Keeping on the backlog.
