So, I am not sure what I am doing wrong. Web searches ran on these error messages did not enlighten me more... Your directory is owned by OS USER sebastien GROUP postgres, try "chown -v postgres /home/sebastien/data " to fix it. The server ( postgres ) does not have permissions ( rwx >>r-x<< r-x, only read and chdir ) to create anything in there. The fact you start psql as sebastien does not matter, it must be owned by the SERVER user ( as psql is separated, it communicates by a socket, can be in another machine ). Francisco Olarte.
