      useFactory: async (configService: ConfigService) => ({
        connectionString: configService.get<string>('DATABASE_URL'),
      }),
      inject: [ConfigService],
    }),
  ],
})
export class AppModule {}

Schedule a job using PgBossService

import { PgBossService } from '@wavezync/nestjs-pgboss';

@Injectable()
export class JobSchedulerService {
  constructor(private readonly pgBossService: PgBossService) {}

    this.logger.log('Handling job with data:', job.data);
  }
}

import { Injectable, Logger } from '@nestjs/common';
import { PgBossService, CronJob } from '@wavezync/nestjs-pgboss';

@Injectable()
export class MyCronJobService {
