Error sqlite2pg script

[Ariane]

When i want to execute sqlite2pg; I have this error

esp@esp-desktop:/var/trac/incidents$ psql ./sqlite2pg -e /var/trac/incidents -p 'postgres://esp:esp@localhost/espdb?shema=test'

psql: could not connect to server: Aucun fichier ou dossier de ce type
	Is the server running locally and accepting
	connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.0"?

in /var/run/postgresql; i have:
drwxrwsr-x  2 postgres postgres 100 2009-08-18 10:59 .
drwxr-xr-x 18 root     root     760 2009-08-18 15:33 ..
-rw-------  1 postgres postgres   5 2009-08-18 10:59 8.3-main.pid
srwxrwxrwx  1 postgres postgres   0 2009-08-18 15:49 .s.PGSQL.5432
-rw-------  1 postgres postgres  34 2009-08-18 15:49 .s.PGSQL.5432.lock

Can you help me please!

This is unrelated to sqlite2pg, this is a simple problem with database connection.
