Upgrade PostgreSQL 9.1 to 9.3 on Ubuntu 12.04

upgrade_pg.sh

echo "deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main" | sudo tee /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.3 postgresql-server-dev-9.3 postgresql-contrib-9.3 -y
 
sudo su - postgres -c "psql template1 -p 5433 -c 'CREATE EXTENSION IF NOT EXISTS hstore;'"
sudo su - postgres -c "psql template1 -p 5433 -c 'CREATE EXTENSION IF NOT EXISTS \"uuid-ossp\";'"
sudo su - postgres -c "service postgresql stop"
sudo su - postgres -c '/usr/lib/postgresql/9.3/bin/pg_upgrade -b /usr/lib/postgresql/9.1/bin -B /usr/lib/postgresql/9.3/bin -d /var/lib/postgresql/9.1/main/ -D /var/lib/postgresql/9.3/main/ -O "-c config_file=/etc/postgresql/9.3/main/postgresql.conf" -o "-c config_file=/etc/postgresql/9.1/main/postgresql.conf"'
 
sudo apt-get remove postgresql-9.1 -y
sudo sed -i "s:5433:5432:g" /etc/postgresql/9.3/main/postgresql.conf
sudo service postgresql restart

Awesome ...It worked Great !

I found that this command has error.

sudo su - postgres -c '/usr/lib/postgresql/9.3/bin/pg_upgrade -b /usr/lib/postgresql/9.1/bin -B /usr/lib/postgresql/9.3/bin -d /var/lib/postgresql/9.1/main/ -D /var/lib/postgresql/9.3/main/ -O "-c config_file=/etc/postgresql/9.3/main/postgresql.conf" -o "-c config_file=/etc/postgresql/9.1/main/postgresql.conf"'

because it tries to run:

"/usr/lib/postgresql/9.3/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/var/lib/postgresql/9.3/main/" -o "-p 50432 -b -c autovacuum_multixact_freeze_max_age=2000000000  -c synchronous_commit=off -c fsync=off -c full_page_writes=off-c config_file=/etc/postgresql/9.3/main/postgresql.conf -c listen_addresses='' -c unix_socket_permissions=0700 -c unix_socket_directories='/var/lib/postgresql'" start

You can see this error in log:

waiting for server to start....FATAL:  parameter "full_page_writes" requires a Boolean value

Therefore I updated it to be like this:

sudo su - postgres -c '/usr/lib/postgresql/9.3/bin/pg_upgrade -b /usr/lib/postgresql/9.1/bin -B /usr/lib/postgresql/9.3/bin -d /var/lib/postgresql/9.1/main/ -D /var/lib/postgresql/9.3/main/ -O " -c config_file=/etc/postgresql/9.3/main/postgresql.conf" -o " -c config_file=/etc/postgresql/9.1/main/postgresql.conf"'

Cool! Thanks!
