Hello, Thank you for all your answers. I did indeed generate a .csv from OpenOffice (Excel could do the job as well) and I imported it into Postgresql using 'copy'. I had to put the .csv files into /tmp to avoid permissions issues but it went fine and fast. To import 45000 lines took about a second. This is impressive...
