Re: [NOVICE] Running .psqlrc from a custom location

I believe you can create a user with the same name as the search_path
schema, so that when you login to the database with that user, and run
commands, the search path defaults to the same name as the user.

I have a system with several schemas and I use a specific USER for each
schema that has the same name as the schema.

ie. schema "demo", user "demo". Login as "demo" and the schema should
default to "demo". Now this may also require that you set the search
path parameter in your configuration file. It is here that you can tell
the system to look for USER, then PUBLIC schemas (in that order) when
someone logs in so the system knows which schema to point the newly
logged in user to.

Keep in mind, I am a novice as well, but this is what I did to get it
working.
