Missing features

[itsbalamurali]

Thank you 🙏 for this amazing project & libraries.

The following are the features I've felt missing while integrating using postgres.

1. Upsert (Update or Insert).
2. Support for array types (TEXT[]).
3. JsonBinary / Json (with or without Option<>) column type generation in code gen.
4. Count method.
5. InsertMany - handle if trying to insert more than 65535 bind paraments. See here
6. json / jsonb select query examples.

For 1 & 2, I was aware of attempts of WIP but they are not completed to a state where it'd readily be merged.
For 4, I think you can use the Paginator helper struct (it has https://docs.rs/sea-orm/latest/sea_orm/struct.Paginator.html#method.num_items)
For 5, I don't know what'd be the ideal solution
For 6, I think there are some test cases in our repo

Do you mean applying db filters (conditions) on JSON column?
