@kapa.ai for postgres it does not see anything in the source schema but the credentials are valid can you explain

This issue could be due to a few reasons. Here are some potential solutions: 1. Check your Postgres version: There have been instances where Airbyte had issues detecting tables from Postgres 14. This issue has been reported on the [Airbyte Github](https://github.com/airbytehq/airbyte/issues/10548). Make sure you are using a compatible version of Postgres. 2. Update your Airbyte version: There was a similar issue reported where Postgres source after 0.4.10 was no longer finding tables in the schema. This issue was resolved in version 0.4.14 as per this [Github Pull Request](https://github.com/airbytehq/airbyte/pull/12689). Updating your Airbyte version might resolve the issue. 3. Check your configuration details: There could be a problem with your configuration details. Even if the credentials are valid, other details might be causing the issue. Make sure all the details are correct. 4. Troubleshoot your Postgres connector: Airbyte provides a [Postgres troubleshooting guide](https://docs.airbyte.com/integrations/sources/postgres/postgres-troubleshooting) that you can follow to troubleshoot your Postgres connector. If none of the above solutions work, I would recommend reaching out to the Airbyte community or support for further assistance.

@kapa.ai will streams appear in a postgres connection if the tables are empt

A message from kapa.ai

Yes, Airbyte will still detect and list the streams (which correspond to tables in a database) in a Postgres connection even if the tables are empty. Airbyte's discovery process checks for the schema and table structure, not the actual data within the tables. Therefore, as long as the tables exist in your Postgres database, they should appear as streams in your Airbyte connection, regardless of whether they contain data or not.

@kapa.ai what permissions does airbyte need for a postgres source

A message from kapa.ai

To set up a Postgres source, Airbyte requires certain permissions for the Postgres user. Here are the permissions needed: 1. Create a dedicated read-only Postgres user: This user should have permissions for replicating data. You can create such a user by running the following commands:

sql CREATE USER <user_name> PASSWORD 'your_password_here';

2. Provide read-only access to relevant schemas and tables: You need to grant this user read-only access to the schemas and tables you want to replicate data from. Run these commands for each schema:

sql GRANT USAGE ON SCHEMA <schema_name> TO <user_name>;   GRANT SELECT ON ALL TABLES IN SCHEMA <schema_name> TO <user_name>;   ALTER DEFAULT PRIVILEGES IN SCHEMA <schema_name> GRANT SELECT ON TABLES TO <user_name>;

3. Provide additional

REPLICATION

permissions for CDC: If you are configuring your Postgres source with Change Data Capture (CDC), you need to grant

REPLICATION

permissions to the read-only user:

sql ALTER USER <user_name> REPLICATION;

Please note that for CDC, you must connect to primary/master databases. Pointing the connector configuration to replica database hosts for CDC will lead to failures.

@kapa.ai does the postgres user need access to any other schemas in addition to the schema it wants to integrate

A message from kapa.ai

The Postgres user only needs access to the schemas that you want to integrate with Airbyte. If you want to replicate data from multiple schemas, you need to grant the user access to each of these schemas. You can do this by re-running the following commands for each schema:

sql GRANT USAGE ON SCHEMA <schema_name> TO <user_name>;   GRANT SELECT ON ALL TABLES IN SCHEMA <schema_name> TO <user_name>;   ALTER DEFAULT PRIVILEGES IN SCHEMA <schema_name> GRANT SELECT ON TABLES TO <user_name>;

Replace

<schema_name>

with the name of the schema and

<user_name>

with the name of the user. Remember, these schema names are case-sensitive. If no schemas are set explicitly, Airbyte will sync all existing schemas for which the user has the necessary permissions.

@kapa.ai why would a a postgres connector see no tables in a source schema

A message from kapa.ai

There could be several reasons why a Postgres connector might not see any tables in a source schema: 1. Insufficient Permissions: The user specified in the Postgres source connector might not have the necessary permissions to access the tables in the schema. The user needs to have

USAGE

and

SELECT

permissions on the schema and its tables. You can check and update these permissions as described in the [Postgres Source Quick Start](https://docs.airbyte.com/integrations/sources/postgres#quick-start) guide. 2. Incorrect Schema Name: The schema name specified in the connector configuration might be incorrect. Schema names in Postgres are case-sensitive. Make sure the schema name matches exactly with the one in your Postgres database. 3. Empty Schema: The schema in your Postgres database might be empty, i.e., it does not contain any tables. Airbyte's discovery process checks for the schema and table structure, not the actual data within the tables. Therefore, if there are no tables in the schema, no streams will be detected. 4. Connector Version Issues: There have been instances where certain versions of the Postgres source connector had issues detecting tables. For example, version 0.4.10 had a [known issue](https://github.com/airbytehq/airbyte/pull/12689) which was fixed in version 0.4.14. Make sure you are using a version of the connector that does not have this issue. If none of these solutions work, consider reaching out to the Airbyte community or support for further assistance.
