Creating 'pcore' PostgreSQL user... psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Connecting to PostgreSQL as 'pcore'...

В файле / etc / passwd нет пользовательского pcore
Может ли это быть причиной того, что postgresql ожидает однозначного соответствия между пользователями linux и postgresql?
Я пытаюсь создать пользователя при возникновении этой ошибки:
# Database imports
import pgdb as psql
# This will create the 'pcore' user using `su` to run the
# command as the postgres system user
def createPsqlPcoreUser(new_pass):
print "Creating 'pcore' PostgreSQL user...",
sys.stdout.flush()
cmd_list = ['su', '-', 'postgres', '-c','psql --host=%s -c '\

(PSQL_SOCKET_PATH, new_pass)]
p1 = subprocess.Popen(cmd_list,
stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
p1.wait()
print p1.communicate()[0]
Дополнительно:
sudo -u postgres createuser pcore -P
Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) y
