PostgreSQL@Ubuntu

Install any version:

• https://wiki.postgresql.org/wiki/Apt
• start: /etc/init.d/postgresql start
• stop: /etc/init.d/postgresql stop

Disc full - PostgreSQL does not start to delete unused DBs

• check space usage (e.g. via: apt-get install ncdu -> ncdu)
• delete unused log files
• temporary reduce reserved space for root
  • check: tune2fs -l /dev/sda2 | grep 'Reserved'
  • reduce reserved % e.g. to 2 (m2): tune2fs -m2 /dev/sda2
  • set back to 5 after fixing space problem tune2fs -m5 /dev/sda2
