point WebStrom to use correct Database class from JSDoc for coding assistance

Try using 

@type {IDatabase}

- this is the interface defined in node_modules/pg-promise/typescript/pg-promise.d.ts

IDatabase does not have methods, that I need. E.g.

db.none

db.one

db.any

they are defined in IBaseProtocol extended by IDatabase

In general - I can not force WebStorm to use "Database" class description from library, right?
And workaround IBaseProtocol - will not work. Looks like Webstorm does not use "typescript" suggestions inside ".js" file.

The same picture you will see with "IDatabase"

Try adding a namespace:

/**
 * 
 * @type {pgPromise.IDatabase}
 */
const db = pgp(config)

Ok. This workaround works! Thanks!
