In recent days, I have been exploring the keycloak, Now I want to change the keycloak default keycloak database to PostgreSQL, For that, I have found a document,
In that document, they mention single-line command to change the default keyclaok database to PostgreSQL.
bin/kc.sh start --db postgres --db-url-host localhost --db-username bennison --db-password bennison
But the above command does not work for me. When I run the above command it throws Unknown option: '--db' error.
If you know the solution for the above error, kindly answer.
Is this the only way to change the database from H2 to PostgreSQL or is there any other way?

I am trying to initialize a database for my project which is based on using apache airflow. I am not too familiar with what happened but I changed my value from airflow.cfg file to sql_alchemy_conn =postgresql+psycopg2:////Users/gabeuy/airflow/airflow.db. Then when I saved the changes and ran the command airflow db init, the error occurred and did not allow me to run the db.
I tried looking up different ways to change it, ensured that I had Postgres and psycopg installed but it still resulted in an error when I ran the command. I was expecting it to run so that I could access the airflow db local host with the DAGs. error occured
Your sql_alchemy_conn is pointing to a local file path (indicating a SQLite DB), but the protocol is indicating a PostgreSQL DB. The error is telling you it's missing a password, which is required by PostgreSQL.
For PostgreSQL, the expected URL format is:
postgresql+psycopg2://<user>:<password>#<host>/<db>
And for a SQLite DB, the expected URL format is:
sqlite:////<path/to/airflow.db>
A SQLite DB is convenient for testing purposes. A SQLite DB is stored as a single file on your computer which makes it easy to set up (airflow db init will generate the file if it doesn't exist). A PostgreSQL DB takes a bit more work to set up, but is generally advised for a production scenario.

I'm trying to connect to an RDS cluster in AWS that's an Aurora PostgreSQL database. It's a brand-new database that I created along with the instances that I have Jira deployed to. However, when I try to connect to the instance from the Jira configuration screen I get this error
You have specified a database that is not empty, please specify an empty database.
I haven't touched this database at all, why is it giving me this error? I have one read and one write database in my cluster and the "hostname" is the endpoint for my write database, which is what the docs say. Could this be an issue with the Jira version I'm using?
This is the download link I'm using in my user-data script to install Jira. I'm also using PostgreSQL version 12.11
https://www.atlassian.com/software/jira/downloads/binary/atlassian-servicedesk-4.19.1-x64.bin
I switched to a different PostgreSQL version and now it's working.
PostgreSQL version 12.11 was giving me the error and switching to version 13.7 works as expected.
I have been introducing myself to Apache Airflow, so far everything is going well however I have been using the default SQLite database and I now need to change to a PostgreSQL database. I have changed the executor to LocalExecutor and I have set the sql_alchemy_conn string to postgresql+psycopg2://airflow:airflow#postgres:5432/airflow which is the address of the airflow database I created in postgres.
Now when I run airflow initdb I recieve the error
airflow.exceptions.AirflowConfigException: error: cannot use sqlite with the LocalExecutor
I am using postgreSQL 9.4.24
Does anyone know why this is occuring?
resolved the issue
I was using the wrong postgres user for the location of the database. Should have been using postgresql+psycopg2://user:user#localhost:5432/airflow
I have the following code to generate the schema for a database in Nhibernate
new SchemaExport(configuration).Execute(true, true, false);
but when run against a PostgreSQL database, I end up getting the following error
[NpgsqlException (0x80004005): FATAL: 3D000: database "dbname" does not exist]
If I however create the database manually, the schema is exported without errors. An so the question: Why is Nhibernate SchemaExport unable to create a PostgreSQL database and yet this works against other databases like SQLite, MsSqlCe and MsSql Server.
I have searched for online literature but have been unable to locate any highlighting on this issue.
I am using Nhibernate 3.3.1 with PostgreSQL 9.2.
You must create the database before you can create the tables and other objects within the database.
Do this with a CREATE DATABASE statement on a PostgreSQL connection - either in your app, or via psql or PgAdmin-III.
PostgreSQL doesn't support creating databases on demand / first access. Perhaps that's what your tool is expecting?
If you think the DB does exist and you can see it in other tools, maybe you're not connecting to the same database server? Check the server address and port.
We have set up postgres 9.0 on our new debian 6.0 server
We want to remotely connect to this database server.
We followed the steps in the below url
http://www.ubuntugeek.com/howto-setup-database-server-with-postgresql-and-pgadmin3.html
But when restart our database it thows the foloowing error
authentication option not in name=value format: sameuser
Any advice on how to access database server remotely using pgadmin 3 would be much appreciated
According to this link, there was changed format of configuration file pg_hba.conf. Remove, please, keyword sameuser from it.
