Strange...I installed the same Kali AMI and used the kali-linux-full metapackage as well and had no problems starting postgresql as you described. Try the following to check installation of postgresql:
Code:
dpkg --get-selections |grep postgresql
You should see the following:
postgresql
postgresql-9.1
postgresql-client-9.1
postgresql-client-common
postgresql-common
If you do not see these try installing with apt-get install postgresql.
I also just took a look at the metapackage with
Code:
apt-cache show kali-linux-full |grep Depends
and noticed that postgresql was missing? Not sure why it is not included in the metapackage. But I suspect that is the issue.
