Hi!
I have centos 6.7 and I have install galaxy.
I setup galaxy.ini with:

database_connection = postgresql://user:password@localhost/galaxydb

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
# IPv6 local connections:
host    all         all         ::1/128               trust
host    all         all         0.0.0.0/0             trust
host    all         all            127.0.0.1/32          trust
host    galaxydb    galaxy  127.0.0.1/32          md5

and I have the database
postgres=# \l
                                   List of databases
    Name     | Owner   | Encoding | Collation |    Ctype    |   Access privileges

                                                               : postgres=CTc/postgres
                                                               : galaxy=CTc/postgres
galaxydb    | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =Tc/postgres
                                                               : postgres=CTc/postgres
                                                               : galaxy=CTc/postgres

what can I do?
