Add support for `stream` parameter for PostgreSQL and MySQL about atdatabases

[ruyadorno]

Thanks for opening this issue @edosrecki! I don't have the bandwith right now to contribute to atdatabases but if anyone is willing to take a try at adding the support to the stream parameter, these are the references to the places I believe have to be tweaked:

• PostgreSQL:

  atdatabases/packages/pg/src/ConnectionSource.ts

  Lines 13 to 27 in bb0dea9

  	export interface PgOptions {
  	user: string | undefined;
  	password: string | undefined;
  	database: string | undefined;
  	connectionTimeoutMillis: number;
  	statement_timeout?: number;
  	query_timeout?: number;
  	idle_in_transaction_session_timeout?: number;
  	application_name?: string;
  	keepAlive: boolean;
  	keepAliveInitialDelayMillis: number;
  	types: TypeOverrides;
  	hosts: {host: string; port?: number | undefined}[];
  	ssl: SSLConfig;
  	}

• MySQL:

  atdatabases/packages/mysql/src/ConnectionPool.ts

  Lines 20 to 37 in bb0dea9

  	interface MySqlConnectionOptions {
  	uri: string;
  	multipleStatements?: boolean;
  	timezone: 'Z' | 'local';
  	typeCast?: (
  	field: {
  	type: string;
  	length: number;
  	db: string;
  	table: string;
  	name: string;
  	string(): string;
  	buffer(): Buffer;
  	geometry(): unknown;
  	},
  	next: () => any,
  	) => any;
  	}
