Sized arrays are supported in various sql dialects.

- [Postgres](https://www.postgresql.org/docs/current/arrays.html#ARRAYS-DECLARATION)
- [Duckdb](https://duckdb.org/docs/sql/data_types/array#examples)




```sql
create table embeddings (data float[1536]);
```

currently this throws an error
```
ParserError("Expected ], found: 1536 at Line: 1, Column 37")
```
