INTERVAL postgres data types have (possibly) incorrect typescript types

[yasiruk]

Describe the bug

Recreated on:

pg typed version: 2.3.0
postgres version: 11.4
pg version: 8.11.3
node version: 18.16.0

pg typed version: master commit:fe3539b6a78fb7ef39b77af081342c30c642660b
postgres version: 16
pg version: 8.11.3
node version: 18

The default configs of pg-typed parses Postgres INTERVAL column data using postgres-interval npm package. This results in types generated for row object properties corresponding to interval results to be of type PostgresInterval that has a shape as follows:

{
"milliseconds" : 0,
"seconds": 1,
"minutes: 10
//....
}

But the corresponding types in the generated type definitions are of string type.

/** 'GetAllMovies' parameters type */
export type IGetAllMoviesParams = void;

/** 'GetAllMovies' return type */
export interface IGetAllMoviesResult {
  duration: string;
  title: string;
}

/** 'GetAllMovies' query type */
export interface IGetAllMoviesQuery {
  params: IGetAllMoviesParams;
  result: IGetAllMoviesResult;
}

const getAllMoviesIR: any = {"usedParamSet":{},"params":[],"statement":"select * from movie"};

/**
 * Query generated from SQL:
 * ```
 * select * from movie
 * ```
 */
export const getAllMovies = new PreparedQuery<IGetAllMoviesParams,IGetAllMoviesResult>(getAllMoviesIR);

Expected behavior

To have consistent compile time and runtime types for corresponding interval values.
