System specification:
Ubuntu 14.04
bucardo version 4.99.10
psql (PostgreSQL) 9.3.14
What I have tried so far?
I have created master database with openerp postgres user.
- Setup Source Database
export SOURCE_HOST=localhost
export SOURCE_PORT=5432
export SOURCE_DATABASE=master
export SOURCE_USERNAME=openerp
export SOURCE_PASSWORD=openerp
- Setup Destination Database
export DEST_HOST=localhost
export DEST_PORT=5432
export DEST_DATABASE=slave
export DEST_USERNAME=openerp
export DEST_PASSWORD=openerp
- Finally, the tables to be migrated
export TABLES="-t res_partner"
export TABLES_WITH_SPACES="res_partner"
- Set up the Destination Database
cat >> $HOME/.pgpass <<EOL
$DEST_HOST:$DEST_PORT:$DEST_DATABASE:$DEST_USERNAME:$DEST_PASSWORD
$SOURCE_HOST:$SOURCE_PORT:$SOURCE_DATABASE:$SOURCE_USERNAME:$SOURCE_PASSWORD
EOL
- Create schema.sql
- Create Slave database
- Load schema into Slave
- Setting up Bucardo Sync (Source Database and Destination Database)
- Now I am trying to add the tables we want to migrate and add them to a "copying herd"
./bucardo add tables res_partner db=master
I got following error:
openerp#odedra-Lenovo-Z50-70:/usr/local/src/bucardo$ ./bucardo add tables res_partner db=master
DBI connect('dbname=master;host=localhost;port=5432','openerp',...) failed: FATAL: password authentication failed for user "openerp"
FATAL: password authentication failed for user "openerp" at ./bucardo line 8632.
I have analytic script bucardo. I have confusion with dbuser and dbpass variable declared at line number 84, 85.
(I have tried with dbuser = 'openerp' and dbpass='openerp' but result same)
My pg_hba.conf
# Database administrative login by Unix domain socket

# "local" is for Unix domain socket connections only
local all all md5

May you guide me what should I change to fix above error or helpful related links?
How can I achieve master-slave functionality using Bucardo ?
I have found that have problem with pg_hba.conf file. To resolve error, I have added below line to that file.
local all openerp ident

I installed

PostgreSQL 13.5 (Ubuntu 13.5-0ubuntu0.21.04.1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 10.3.0-1ubuntu1) 10.3.0, 64-bit
(1 row)
and I want to create connection for my project(java, php, what ever) so for that I followed in user guide
CREATE ROLE admin WITH SUPERUSER LOGIN CREATEDB CREATEROLE ENCRYPTED PASSWORD '111';
and right now faced with that

So, after that
CREATE DATABASE spd_talks;
and faced with

and provide all grant

then admin was added to Access privileges column

then I try to connect to spd_talks db by admin user and faced with error
ivan#ivan-laptop:~$ psql -U admin spd_talks
psql: error: FATAL: Peer authentication failed for user "admin"
the same case when I try to did it by IDE
what I missed, how to correct create user with db and connect by him?
I changed
local all postgres peer
to
local all postgres md5
in
sudo gedit /etc/postgresql/13/main/pg_hba.conf
but still faced
ivan#ivan-laptop:~$ psql -U admin -d spd_talks
psql: error: FATAL: Peer authentication failed for user "admin"
UPDATE
when I changed
local all all peer
to
local all all md5
I faced with successful connection by console
ivan#ivan-laptop:~$ psql -U admin -d spd_talks
Password for user admin:
psql (13.5 (Ubuntu 13.5-0ubuntu0.21.04.1))
Type "help" for help.
spd_talks=#
but still error in ide
I resolved this missundertood by
spd_talks=# \conninfo
You are connected to database "spd_talks" as user "admin" via socket in "/var/run/postgresql" at port "5434".
and I don't now why but port is 5443, then I canged it in ide and it works
I've just installed a PostgreSQL 10 on Ubuntu 18.04. I have postres default user setup with a password.
I created some users and databases but I'm getting this error. How do I get passed this?

I verified they exist:

Here's my etc/postgresql/10/main/pg_hba.conf. Notice I have DB admin set to md5 instead of peer in case this matters.

I'm setting up postgres on DigitalOcean. I've set PG envs. The 9s are obviously redacted data. To facilitate the ssl connection, ~/.postgresql/root.crt exists.
# env | grep PG

PGUSER=doadmin
PGDATABASE=auth_service_prod

When calling createdb, it fails:

createdb: could not connect to database template1: FATAL: pg_hba.conf rejects connection for host "10.999.9.99", user "doadmin", database "template1", SSL on
I can connect to psql, though. I don't know enough about configuring postgres to allow doadmin to create a db, but hopefully here is some useful info:

DigitalOcean doesn't allow createdb from postgres, apparently. I removed the code creating databases, and created them "manually" from their GUI. The app is now only responsible for managing the schema, not the database(s).
I created a Postgres database this way:
createdb massive
Then I added a role:
sudo -iu postgres
psql -d massive
CREATE ROLE rob WITH SUPERUSER CREATEDB CREATEROLE LOGIN ENCRYPTED PASSWORD 'password';
I quit psql with \q, then exit user postgres.
Now I try to login:
psql -U rob -d massive -h localhost -W
When entering password at the password prompt, I get this:
psql: FATAL: password authentication failed for user "rob"
Update:
\lin psql returns this:

I want to import a database of mine to a database of my server. So, I copied my database dump file to my server's root directory and logged in and did this:
root#iWidgetServer1:~# sudo -u postgres psql -U iwidget -d iwidget -f iwidget_dump2.sql
could not change directory to "/root"
psql: FATAL: Peer authentication failed for user "iwidget"
However, iwidget is a role and has granted all priviliges for this database:
root#iWidgetServer1:~# sudo -u postgres psql -l
could not change directory to "/root"

What am I doing wrong?
From the docs:
The peer authentication method works by obtaining the client's operating system user name from the kernel and using it as the allowed database user name (with optional user name mapping). This method is only supported on local connections.
You're doing sudo -u postgres, but are trying to connect as iwidget.
You need to create a user named iwidget and login as this user.
This seems to be more a problem with the File permissions of the dump instead of Postgres. Have you tried moving the dump to a folder not owned by root?
