can't pg_dump the PostgreSQL db. config help?

[D Mitchell]

So over the last couple of upgrades to Jira, we've had to upgrade PostgreSQL as well for compatibility.     So we're now at:

Jira 8.20.1

PostgreSQL 10

But when I try to dump the db, it complains (I'm running this as root if that matters, it didn't used to):

-bash-4.1$ pg_dump -U jiradbuser jiradb -f jira-11-06-18.sql
pg_dump: [archiver (db)] connection to database "jiradb" failed: FATAL: Peer authentication failed for user "jiradbuser"

Seems like a config issue, so here is my:  /data/pgsql/10/data/pg_hba.conf

# TYPE DATABASE USER ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 ident
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all peer
host replication all 127.0.0.1/32 ident
host replication all ::1/128 ident

What am I missing here?   Any thoughts?

Thanks in advance.

This is what it says it is - your jiradbuser did not authenticate with the credentials you have used.   

I note that your command doesn't contain anything to do with the password that you should have set on the database for that user.
