- PostgreSQL Extension 12552
- The postgres extension allows DuckDB to directly read and write data from a running PostgreSQL database instance. The data can be queried directly from the underlying PostgreSQL database. Data can be loaded from PostgreSQL tables into DuckD
...tables, or vice versa. See the official announcement for implementation details and background. Installing and Loading The postgres extension will be transparently autoloaded on first use from the official extension repository. If you would like to insta...ll and load it manually, run: INSTALL AND LOAD postgres; Connecting To make a PostgreSQL database accessible to DuckDB, use the ATTACH command with the postgres or postgres_scann...er type. To connect to the public schema of the PostgreSQL instance running on localhost in read-write mode, run: ATTACH '' AS postgres_db (TYPE postgres); To connect to the Postg... - https://man.mtool.work/duckdb/2.0/core_extensions/postgres/overview.html
- PostgreSQL Extension and the Secret Manager 11431
- User credentials and other PostgreSQL database connection details can be stored using the DuckDB Secrets Manager . The following syntax can be used to create a secret: CREATE SECRET ( TYPE postgres, HOST '127.0.0.1', PORT 5432, DATABASE postgres
...tgres, USER 'postgres', PASSWORD '' ); The information from the secret will be used when ATTACH is called. We can leave the PostgreSQL connectio...n string empty to use all of the information stored in the secret. ATTACH '' AS postgres_db (TYPE postgres); We can use the PostgreSQL connection string to override individual options. For example, to connect to...using the same credentials, we can override only the database name in the following manner. ATTACH 'dbname=my_other_db' AS postgres_db (TYPE postgres); By default, created secrets are temporary.

- Amazon RDS with IAM Authentication 10914
- Managed PostgreSQL databases on Amazon RDS and Aurora can authenticate with short-lived IAM tokens instead of a static password. DuckDB supports this through the postgres and aws extensions: the aws extension generates the token from an AWS
