I can get all databases in the same server with the function databaseMetaData.getCatalogs() and all the tables in any database in any schema with the function databaseMetaData.getTables("databaseName", "schemaName", null, null).
databaseMetaData.getSchemas() function provides only the schema names of connected database given in the connection String. Is there a way to get schema names of other databases in the same server?
I'm setting up postgres backend for Airflow metadata DB using the following sqlalchemy connection string:
sql_alchemy_conn = postgresql+psycopg2://<user>:<pass>#<host>:5432/<db>
When I run initdb/upgradedb, the tables are created in public schema.
Is there a way to create the tables in a specified schema?
Can the schema where I would like the tables to be created be specified as part of the connection string?
From the docs:
Also note that since SqlAlchemy does not expose a way to target a specific schema in the Postgres connection URI, you may want to set a default schema for your role with a command similar to ALTER ROLE username SET search_path = airflow, foobar;
So, connect to postgres, and set the search path for your user.
I am connecting spring boot application to PostgreSQL database. I have created the table using "create query tool" of PostgreSQL. It has been put in the default public schema. But when I tried to insert values in table, it does not accept values.
I have used the following command:
Insert into User values(1,"ABC","pass_1");
What is the proper way to insert?

DB Version 9.6.3
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.
