Force Installing to Upgrade Extensions
When DuckDB installs an extension, it is copied to a local directory to be cached and avoid future network traffic.
Any subsequent calls to `INSTALL ⟨extension_name⟩` will use the local version instead of downloading the extension again. To force re-downloading the extension, run:  
```sql
FORCE INSTALL extension_name;
```  
Force installing can also be used to overwrite an extension with an extension with the same name from another repository,  
For example, first, `spatial` is installed from the core repository:  
```sql
INSTALL spatial;
```  
Then, to overwrite this installation with the `spatial` extension from the `core_nightly` repository:  
```sql
FORCE INSTALL spatial FROM core_nightly;
```
