TS Errors in Custom Type citext example

I want to include citext data type in my postgres schemas. I was delighted to see there's a complete example in the docs (https://github.com/drizzle-team/drizzle-orm/blob/main/docs/custom-types.md#citext-data-type-example) However, it seems to be broken - see screenshot - because I'm getting a bunch of TS errors. Something on my side or is it outdated? Edit: to give a bit more context, the errors all seem to be originating, for now at least, from this error on PgColumnBuilder:

Generic type 'PgColumnBuilder<THKT, T, TRuntimeConfig, TTypeConfig>' requires between 2 and 4 type arguments.ts(2707)

Generic type 'PgColumnBuilder<THKT, T, TRuntimeConfig, TTypeConfig>' requires between 2 and 4 type arguments.ts(2707)

So to use citext would be as simple as:

import { customType } from "drizzle-orm/pg-core";

export const citext = customType<{ data: string }>({
  dataType() {
    return "citext";
  },
});

import { customType } from "drizzle-orm/pg-core";

export const citext = customType<{ data: string }>({
  dataType() {
    return "citext";
  },
});

Or would we need to more explicit with the driver types? Do they default to the data type?
