Fix DB errors of an open source project running in production

I am very proficient in java. I have 16 years java developing experience now, and have worked for more than 6 years. My work is online game developing, and mainly focus on server side, using java under linux environment. I used java to make many great projects, for example, I made the tools which can convert java files into c++ scripts, of course garbage collection included, this job is very similar to a compiler, and is very complex. I also made our own mobile game using java, I can show you the demo of client, if you like. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you. Besides, I am very proficient in c++ also, hope I can help you.

Hi, I’m a London-based software engineer and system administrator with more than 10 years of experience working on enterprise level applications built with Python, Java and PHP. I can start working on your project right now and I'm sure that I'll be able to sort it really quickly. If you have any questions feel free to ask me via freelancer chat.

As discussed the scope of work is to troubleshoot the problem for 2 hours. I don't guarantee the outcome. However, I'll do my best to solve the problem in this timeframe. Meeting time - 9:30 PM - 11:30 PM IST or 4pm-6pm UTC.

Hi, my name is Matt Sergej and can help you (22 years of IT development and webmastering). I'm not in PostgreSQL "waters" in last years but errors like this are usually solved by: 1. Establishing a connection first using a command line. This might involve checking and setting the correct port (if you have changed the default). 2. Then checking the security credentials and confirming they work. 3. And finally ensure all dependencies and drivers are resolved without errors. I'm pretty sure updating your PostgreSQL and/or Java drivers will resoive the error. If you need help, I might provide it if I'm free next days. Regards, Matt
