I've had as few issues trying to upgrade postgresql-server. I've reverted back to the older version now (9.0.3) and the service is running and accessible via pgadmin/other gui tools. Primary Phonics Set 1 Download on this page. However, I can't access it via the psql command (as user postgres). This may be possibly because the psql binary seems to be missing. I feel this may have happened when I uninstalled a version of postgres that I had intended to revert to. I can't reinstall version 9.0.3 because the repo is no longer valid. Is there any way I can install only the psql binary file and nothing else.

I was considering copying the psql binary file from another server, although because the other servers have different versions of postgresql, I'm not sure if this is a good idea (?).

Installing SuperSU — I found a binary. When I use 'install' in TWRP and click on the zip file. Is no SU binary installed, and SuperSU cannot install.
