1) The appropriate list for this sort of question is pgsql-general:

https://www.postgresql.org/list/pgsql-general/

2) In addition to Christophe's suggestion:

Check your pg_hba.conf file for a uncommented line like:

local   all             postgres                                trust

If it is there then you can on the server machine do:

psql -d database -U postgres

to make a local connection via socket without a password.

If it is not there then add it and reload the server settings.
