Thank you Aditya for responding. I don't think there is any log file since it doesn't open even once. I have checked it and didn't find any. It worked fine on my own system but just causing issues in opening up in my AWS EC2 instance.
I have installed pgAdmin along with PostgreSQL setup. I have also tried installing it separately but the same issue every time it doesn't launch. -- Sent from: https://www.postgresql-archive.org/PostgreSQL-pgadmin-support-f2191615.html
