I've upgraded my JIRA Core to 8.0.2 from 7.x and it gave me PostgreSQL locale error.
Your postgres72 database is currently using an unsupported collation: en_US.UTF-8. You should change this to a supported collation:
First, I'm using PostgreSQL 9.6, not 7.2. Second I have to support UTF-8. But when I ask my computer for available locales; even it has C and POSIX, it does not have UTF-8 versions. BTW my OS is CentOS 7.
I'm trying to find a way to add C.UTF-8 to my OS but couldn't yet. Maybe you can help.
Thanks.
