Installing PostgreSQL. How to configure pg_hba.conf and postgresql.conf?

Question

linux

When I enter the command psql -U postgres
, I get the following output

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"?

I googled that the problem is in the posgresql and pg_hba configs. In the first, everything is by default, it listens to localhost, port 32. But with the second problem, I tried in different ways, but it does not work out. As a result, rolled it back to the default state.

local   all             postgres                                all

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                trust
#host    replication     postgres        127.0.0.1/32            trust
#host    replication     postgres        ::1/128                 trust

Looking for wise advice

Answer 1

First of all, postgres does it work?
Secondly, remove or put in trust
There is no such type of authorization all

Answer 2

If it listens to a non-standard port, then you need to connect like this
. Try to also comment out everything, leaving
and gradually add on the line that makes sense.
Well, after each change of settings, do not forgetservice postgresql restart
