Postgresql: connexion to a specific schema

HI mattschaer and thanks for your reply
Well in postgresql you can create multiple schemas within one database.
MY goal is to create one service in dreamfactory from one specific schema available in a postgresql database.
When creating a dreamfactory service from an existing postgresql database, i can only see tables coming from the default “public” schema available in postgresql databases.
That s why i m asking myself if it could be possible to create a service connected to a specific schema available in my postgresql database.
Hope i ve been a bit clearer…sry for my english…
