error connection postgresql 9.0

Hi!

I have problem to connect in Postgres 9.0 version with sequelize. Show me an error about not exist ‘pg_range’ (error message: ‘relation “pg_range” dows not exist’).

When I try connect in Postgre 9.5 it works (because 9.5 have pg_range on pg_catalog). How can I connect in Postgres 9.0??

const sequelize = new Sequelize(
      'DatabaseTest',
      'postgres',
      'postgres',
      {
        host: '[ip]',
        dialect: 'postgres',
        port: 5432
      }
    );
    sequelize
      .authenticate()
      .then(() => {
        toast.success('Conexão realizada com sucesso!');
        return true;
      })
      .catch(err => {
        toast.error(`Não foi possível conectar na fonte de dados ${err}`);
      });

To Reproduce Just try connect!

is this problem still persisting? i am trying to connect to a postgres db version 8.x through sequelize and i get the same error message as @fabio-basedev unfortunately i cannot find any documentation on PG version compatibility of sequelize so i can’t figure out whether postgres 8.x is too low for sequelize 5.x

any clue?

i have solved this, by downgrading sequelize to the deprecated version 4.44 it seems to work.

hope they will improve their documentation, it took me quite a while to figure that out.

thanks @SimonSchick for your message, that helped me out
