 #### Can I store vectors with different dimensions in the same column?
 
-You can use the `vector` type (instead of `vector(3)`). However, to index the column, you’ll need to use an [expression](https://www.postgresql.org/docs/current/indexes-expressional.html) to set the number of dimensions and a partial index to filter rows with different dimensions.
+You can use the `vector` type (instead of `vector(3)`).
