We have a PostgreSQL which is installed in openshift container DB.
I wanted to fetch data from few tables in Postgres Db(PostgreSQL) and load it to Oracle Db.
Please give me some idea on how to connect and fetch the data from Postgres.
Thanks!

I am trying to query data between two servers of postgres. One is posgtres RDS of AWS and one is a aurora DB postgres. This posgtres RDS of AWS is a backup of the main aurora DB. I need to copy few rows from this backup to the main aurora Db instance.
i tried using dblink to connect two servers but it is not successful
I tried using dblink and it did not work. My postgres version is latest and above 13.6 and it is aurora serverless V2.
I created a Data Federation Database Instance like below:
I can connect to it from DBeaver, but when I tried to insert/update the data, it cause an error:
How can I update/insert mongodb from DBeaver?
I created an RDS Postgres instance. I'm new to RDS.
db host:
demodb.xxxuxxvxxxxx.us-east-2.rds.amazonaws.com
db identifier:
demodb
Every tutorial says to connect with this URL:
jdbc:postgresql://demodb.xxxuxxvxxxxx.us-east-2.rds.amazonaws.com:5432/demodb
but every time I do I get this error-
FATAl: database "demodb" does not exist.
I am able to connect using this:
jdbc:postgresql://demodb.xxxuxxvxxxxx.us-east-2.rds.amazonaws.com:5432/postgres
Now, while I was excited to connect after I used SQL workbench to create tables and insert data into those tables, a few hours later all my tables and data were deleted/wiped/dropped. Why would this happen? and How can I prevent it from happening in the future?
FATAl: database "demodb" does not exist.
demodb is db instance identifier. It is NOT the name of your database inside of PostgreSQL.
By default RDS PostgreSQL does not create a database for you. It seems to me that you haven't created an actual database when you setup your RDS PostgreSQL.
To create a database at RDS creation there is an option called Initial database name where you should specify the name of the database you want. Otherwise, no database is created, which is a default behavior:
I am writing a JUnit test which needs an in-memory database.
We are using PostgreSQL database and it can't be used as in-memory database.
Could you provide any suggestions on how to restore a PostgreSQL schema dump into different in-memory database (eg: Apache Derby, H2)?
I need to update a dababase from an other database... For this I need to search in existing database if the records exists, if not add... One of the database is locally stored in my computer, and the other one is on heroku... But I don't know how to access heroku database from my computer to create the inserts and to query if I have to insert or not...
Any idea how can I do something like this?
You can connect via any DB tool, e.g. Oracle SQL Developer with Postgres JDBC connector, to a Heroku Postgres DB. The parameters are listed in the GUI of postgres.heroku.com for your instance.
