The problem is that rubber creates the DB user as NOSUPERUSER
. My workaround is to create tasks that run before and after capistrano's deploy:migrate
that will change the user to SUPERUSER
and back.
Here's the code:
namespace :rubber do
namespace :project do
before "deploy:migrate", "rubber:project:add_pg_superuser_and_enable_hstore"
after "deploy:migrate", "rubber:project:remove_pg_superuser"
task :add_pg_superuser_and_enable_hstore,
:roles => [:postgresql_master, :postgresql_slave] do
alter_user_cmd = "ALTER USER #{rubber_env.db_user} SUPERUSER"
create_hstore_cmd = "CREATE EXTENSION IF NOT EXISTS hstore;"
rubber.sudo_script "add_superuser_create_hstore", <<-ENDSCRIPT
sudo -i -u postgres psql -c "#{alter_user_cmd}"
sudo -i -u postgres psql -c "#{create_hstore_cmd}"
ENDSCRIPT
end
task :remove_pg_superuser, :roles => [:postgresql_master,
:postgresql_slave] do
alter_user_cmd = "ALTER USER #{rubber_env.db_user} NOSUPERUSER"
rubber.sudo_script "add_superuser_create_hstore", <<-ENDSCRIPT
sudo -i -u postgres psql -c "#{alter_user_cmd}"
ENDSCRIPT
end
end
end
