Answer 1

It typically indicates that there is another open PostgreSql connection. To bubble up the right error try % rake db:test:prepare

Running test prepare showed the following below and when the open connection (PGAdmin in my case) was closed the issue was resolved.

rake aborted!
PG::Error: ERROR:  database "xyz_test" is being accessed by other users
DETAIL:  There are 1 other session(s) using the database.
: DROP DATABASE IF EXISTS "xyz_test"

Tasks: TOP => db:test:load => db:test:purge
