Mikro-orm error: password authentication failed for user "postgres"

Question

I'm trying to code along this React GraphQL TypeScript tutorial

The project uses MikroOrm to communicate with a PostgreSQL database. I have PostgreSQL(12.4) installed on my Ubuntu 18.04, created a "postgres" user and I can log in to the user and run psql without any problems. However, when I start using mikro-orm commands like npx mikro-orm migration:create (video timestamp), I get the following error:

error: password authentication failed for user "postgres"

Here is the error in PostgreSQL log file:

2020-08-28 01:45:18.218 EEST [23088] postgres@newstack FATAL:  password authentication failed for user "postgres"
2020-08-28 01:45:18.218 EEST [23088] postgres@newstack DETAIL:  Password does not match for user "postgres".
    Connection matched pg_hba.conf line 96: "host    all             all             127.0.0.1/32            md5"

And here is my pg_hba.conf:

local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

local   all             all                                     peer
host    all             all             127.0.0.1/32            md5
host    all             all             ::1/128                 md5
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5

I have figured that if the connection would've been local, then it wouldn't have required a password, but why isn't it using local socket? If that can't be changed, then how can I give MikroOrm my database credentials?

Answer 1

Change "md5" to "trust" like this:

local   all             all                                     peer
host    all             all             127.0.0.1/32            trust
host    all             all             ::1/128                 trust
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5

Answer 2

For me it's worked after i'am added

clientUrl: 'http://localhost:5433'
user: 'postgres',
password: <user pasword for postgres user>

in options object
