Allow another schema than « public » for Langchain SQL Agent with PostgreSQL

The idea is:

Add the ability in AI node for SQL Agent to allow for another schema than “public” for postgreSQL. The feature list-tables-sql returns only public tables. Langchain standard feature enables to select another schema.
Can you please add this feature ?

My use case:

Interact with LLM and sql DB where the data is not stored in “public” schema.

I think it would be beneficial to add this because:

One often does not use the public schema by default

Any resources to support this?

Just a schéma argument in Langchain

Are you willing to work on this?

No

You can simply define the schema name followed by the default table name that n8n creates to save chat histories.

Like in this example:
