SQL Populate table with random data

I have a table with two fields:

  1. id(uuid) that is primaryKey and

  2. description (var255)

I want to insert random data with sql sentance.
I would like that description would be something random.

Can some1 please help me with this?

PS: im using postgresql.


I dont know exactly if this fits the requirement for a "random description", and it's not clear if you want to generate the full data: but, for example, this generates 10 records with consecutive ids and random texts:

  test=#  SELECT generate_series(1,10) AS id, md5(random()::text) AS descr;

     id |               descr
      1 | 65c141ee1fdeb269d2e393cb1d3e1c09
