I have created a new Arora Serverless PostgreSQL cluster and I am trying to use the Query Editor.
What do I enter in the Database Name text field? Where do I find the name of the database? Is it the same are the cluster name?
Note: I have enables the Data API when I created the DB
Creation of database is an optional setting when you create your Aurora serverless:
If you haven't done that you have to create your db using traditional way.
This is the name of the database within the cluster, not any hostname or individual node. The target hosts are specified in Database instance or cluster label.
When you created your database cluster you could optionally specify a database that would be created on the host. This default database is viewable from within the console interface. Otherwise if you created the target database after the cluster launched, specify that database name instead.

I'm creating an RDS postgreSQL 10.6 instance and when I name it the name does not save.
I can add a database name when creating the instance:
But after it's created the name doesn't seem to be saved :
Note DB name is blank. RDS bug or am I missing something?
Although I didn't find the reason why my custom name does not apply, the default database name is postgres so now I can connect with my client
I have created a AWS RDS Postgresql db instance in one VPC and I need to "move" it to another VPC.
I created a snapshot of the original db instance.
Re-created it in a new VPC (using terraform).
How can I retrieve one particular database from my initial db instance snapshot into the new DB Instance?
When you restore snapshot all databases are restored.
If you want to copy particular database, AWS service Database Migration Service can be used if postgres version is higher than 9.4.
https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.PostgreSQL.html
If postgres version is lower, then only manual export/import of database can be used. Another instance where export files will be stored is needed.
Whenever I create a Db2 service in IBM Cloud, it takes the default database name BLUBDB. I want to change to user specific name like TESTDB?
Most of service plans for Db2 Warehouse on Cloud (formerly dashDB), then there is only a single database and the name is preset to BLUDB for simplicity. If you want to have more control, you could go with Db2 Hosted on IBM Cloud.
Alternatively, if you are already locally cataloguing the database you could add an alias.
For example:
db2 catalog tcpip node mynode remote dashdb-myinstance.bluemix.net server 50000
db2 catalog database bludb as testdb at node mynode
I want to understand AWS Relational Database Service (RDS) and discover benefits from using it.
Why RDS is better than manually installed PostgreSQL database in EC2 instance?
Is it possible to connent existing database in EC2 instance with Amazon RDS?
How it really works?
How I should automation RDS?
When I want create new database in existing EC2 instance I can use Ansible in simply way. How I should connect my application with database which uses RDS ?
Thanks in advance!
I want to understand AWS Relational Database Service (RDS) and discover benefits from using it.
As already commented, read the docs and whitepapers.
Why RDS is better than manually installed PostgreSQL database in EC2 instance?
you can be sure it is well setup, you will get point in time recovery, backups and high availability. As well you can set it up yourself, however using RDS you have it all already configured.
Ifs it possible to connent existing database in EC2 instance with Amazon RDS? How it really works?
you don't have access to any underlying configuration, so nope, you cannot really connect ec2 database w/ rds (e. g. wal for wal streaming).
you still can use database migration tools to migrate all databases and updates to or from rds
How I should automation RDS? When I want create new database in existing EC2 instance I can use Ansible in simply way.
you can use a cloudformation template or cli commands
How I should connect my application with database which uses RDS ?
when you create a rds instance, you will define an admin user and receive a connection url

Many suggestions for integration testing which includes Postgres Database say that I can initdb a new whole cluster in RAM disk and work on it.
As far as I understand initdb is a new folder like thing related to databases.
According to Postgres docs:
initdb creates a new PostgreSQL database cluster. A database cluster is a collection of databases that are managed by a single server instance.
Does it create a new server? Or a new Database?
Creating a database cluster consists of creating the directories in which the database data will live, generating the shared catalogue tables (tables that belong to the whole cluster rather than to any particular database), and creating the template1 and Postgres databases. When you later create a new database, everything in the template1 database is copied. (Therefore, anything installed in template1 is automatically copied into each database created later.) The Postgres database is a default database meant for use by users, utilities and third party applications.
Does the above sentence mean that from now on whatever database is created it is stored in that new "cluster"? If not how to create tables in such a cluster of RAM disk?
How can I use it to set it up for testing?
In the terminology your image uses (from pgAdmin?), initdb would create the data directory for a new “server”.
In PostgreSQL, this is not called a server, but a database cluster. It has a data directory, which is created with initdb. If you start the cluster with pg_ctl start, a PostgreSQL server process (called postmaster) is started, which listens for incoming connections and starts backend processes that work on the data directory.
There can be more than one PostgreSQL database clusters on one machine, you just have to give them different port numbers.
It should be no problem to run initdb to create a database cluster for your integration tests. After initdb you have to edit postgresql.conf appropriately (e.g. to set port) and start the postmaster with pg_clt start -D <data directory>.
