    Default Backing up postgres database for use in java program eclipse

    Hello, so I have googled this and can't really get a straight answer that I understand. I have a postgres database. I have to export it or save it so I can use it with a java app I am developing. What format should I export it as? .sql .db? Do I do that by using the dump command? I am on ubuntu 18.04 and also using PgAdmin4 with it. I have been able to get a .backup file made but I am confused as to which is transferrable and able to be used with a eclipse/a java program. I do have the latest postgres JDBC for it installed on my version of eclipse.

    Thank you in advance.

    Edit**This is just localhost

    Are you trying to migrate the database locally? You just need to dump the database and feed it back into your new instance. This is independent from Java/Eclipse.

    Here's more info:

    No, I am working on a project with other people. So I need it to dump it so I can use with other versions possibly. I'm not too experienced with it so yes, that may be what I need. So does the dump command in the link you showed me give just something like TestDB? No .sql or .db? I ran the command and now I cannot find the file. Do you know where it would be in ubuntu by any chance? I have tried var/lib/postgresql/10/main and also the etc path. Is there another command that would let me specify where it goes?
