RedBeanPHP does not support other schemas than the public one.
I don't see the use of multiple schemas in Postgres, no other database does
RedBeanPHP thinks in databases, not schemas. You can still use schemas but
not with the default
RedBeanPHP functions. While I agree you should use the full power of your
database I think there is a limit to this.
For instance Postgres also supports table inheritance, yet RB will not
support that either.
I feel it's important to keep a clear focus and to support basic database
features not very specific ones.
Of course maybe someone will write a plugin or a QueryWriter object that
makes this possible.
