When you divide a database into multiple, you must provide the
referrals to glue it together and use clients which chase referrals.
In addition, if the referral returned is to a "different" server
as determined by the client, the client must rebind when chasing
the referral.  The command line tools do not rebind so only
work if the referral is to "original" server.

Note:  a client which connects localhost is likely consider
any referral to be "different".

No.  Operations do not span databases.  However, the client can
chase referrals the server provides.

Not sure what you're asking here... I'll assume my comments
above answered the question.
