Permit

I'd like to set them up like that based on the Policy Performance recommendations.

I am using the postgres fetcher to get the data here, but I'm not sure if that's something that need be handled in the logic of the specific fetcher

Hi I think you can use the `"fetch_one": True` config entry to set achieve that.
And of course you can customize things even more by forking the fetcher and editing that process method:

```fetch_one: bool = Field(
        False,
        description="whether we fetch only one row from the results of the SELECT query",
    )```
This actually only returns the first item from the list

I’ll ask <@U033FPT0BFH> to review :slightly_smiling_face:

Just realized that this PR <https://github.com/permitio/opal-fetcher-postgres/pull/12>
does the same thing as what I implemented but was never merged... which is probably why you thought it was already there <@U01RH8JQKHD>

:sweat_smile: - good catch

<@U02CN8CVBJL> I’d leave pruning for you here
