A list of log levels to log or a custom logger function.

Currently there's only two levels: query and error. This will be expanded based on user feedback later.

Examples

const db = new Kysely<Database>({
  dialect: new PostgresDialect(postgresConfig),
  log: ['query', 'error']
})

const db = new Kysely<Database>({
  dialect: new PostgresDialect(postgresConfig),
  log(event): void {
    if (event.level === 'query') {
      console.log(event.query.sql)
      console.log(event.query.parameters)
    }
  }
})
