As pointed by Douglas from your file [Alfresco tomcat and postgres error.txt] there seems to be DB issue.
But looking into [alfrescotomcat-stdout.2014-06-27.log] it says Alfresco was able to connect to your postgres instance and then it failed while starting up the CIFS subsystem.
2014-06-27 05:47:53,724 INFO [domain.schema.SchemaBootstrap] [localhost-startStop-1] Connecting to database: jdbc:postgresql://localhost:5432/alfresco, UserName=alfresco, PostgreSQL Native Driver

2014-06-27 05:48:03,880 ERROR [org.alfresco.fileserver] [localhost-startStop-1] CIFS server configuration error, 05270001 CIFS Domain name must be specified if host announcement is enabled
org.alfresco.error.AlfrescoRuntimeException: 05270001 CIFS Domain name must be specified if host announcement is enabled
I would suggest you to disable the CIFS subsystem by adding -
cifs.enabled=false
in tomcat\shared\classes\alfresco-global.properties Please do restart the server after adding this line.
