Yes

Please describe.

The postgres connection in PostHog (Sync to Warehouse) currently allows one schema per connection. If a postgres DB has multiple schemas, users have to set up a separate connection in PostHog for each schema. Our database is designed to have one schema for each of our clients and we have 1000+ schemas in our database. It is super manual and not scalable to create 1000+ connections in PostHog to bring data from all the schemas.

Describe the solution you'd like

The Ideal solution: the Postgres connnection in PostHog allows users to select all the schemas or multiple schemas. Once the connection is set up, users can query data from any or all schemas inside PostHog.

It would be great if there is an automated way to consolidate (union all) tables from all schemas into master tables

Describe alternatives you've considered

Airbyte + Snowflake + dbt to consolidate (union all) tables from all schemas into master tables and then bringing those master tables into PostHog. But this creates additonal steps, layers and costs
