Finally there was no real dependencies of that table, and I've found out
that the "dependency" was my function ! Using SETOF (table) makes
impossible to DROP the table. Therefore I DROP my function and was able
to follow you advice, and it worked perfectly !

Thanks a lot for your help (as well as Richard's)
