Ident authentication failed

Hi,

I'm trying to configure miniflux and am struggling to figure out how to
configure postgres for that purpose.  (The miniflux instructions are
very terse.)  Regardless of whether I run the command as the postgres
user or the miniflux user, I get similar errors.  I am running Centos 7
using the updated scl version of postgres (9.6.10).

With the following, the postgres user "miniflux" along with the password
are specified in /etc/miniflux.conf.

$ miniflux -c /etc/miniflux.conf -migrate
Current schema version: 0
Latest schema version: 26
Migrating to version: 1
[FATAL] [Migrate] pq: Ident authentication failed for user "miniflux"

I have no problems logging into postgres as the miniflux user using the
same password specified in /etc/miniflux.conf.

Running the same command without specifying the configuration file uses
the postgres user and also fails

$ miniflux -migrate
[INFO] The default value for DATABASE_URL is used
Current schema version: 0
Latest schema version: 26
Migrating to version: 1
[FATAL] [Migrate] pq: Ident authentication failed for user "postgres"

My /var/opt/rh/rh-postgresql96/lib/pgsql/data/pg_hba.conf file includes

# TYPE  DATABASE        USER            ADDRESS METHOD

local   miniflux   miniflux      trust
local   miniflux   postgres      trust

# "local" is for Unix domain socket connections only
local   all             all peer
# IPv4 local connections:
host    all             all             127.0.0.1/32 trust

I'm at a complete loss.

Any suggestions?

Thanks,

Ted To
