This shouldn't matter.

Yup, if you set up trust authentication in your pg_hba.conf file
correctly. Or you can also create a ".pgpass" file from which psql can
load its password automatically, see:

To recap, you can either create the .pgpass file mentioned above, or
you can fix your pg_hba.conf file to trust local connections (or
connections from whatever machine you're connecting from). Here are
some common pitfalls I can think of that you might want to double
check
* did you remember to use "pg_ctl ... reload" or some other means to
notify Postgres that you've changed its pg_hba.conf file?
* maybe you're connecting to Postgres from a different address than
you specified in the Address field of pg_hba.conf? Set log_connections
=3D on in your postgresql.conf and run pg_ctl ... reload to have
Postgres print what address it actually sees your connections coming
from in its log.
* If you are using psql to connect to a Postgres server on the same
machine, and you would like to trust all users on that machine to
login to Postgres as a superuser, your pg_hba.conf should have lines
like this:
# "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
If you're still having trouble, post the uncommented lines from your
pg_hba.conf file, and also post lines about connection attempts from
your PostgreSQL server log file after you've turned on
log_connections.
