From here:
https://www.postgresql.org/docs/current/libpq-envars.html
"The following environment variables can be used to select default
connection parameter values, which will be used by PQconnectdb,
PQsetdbLogin and PQsetdb if no value is directly specified by the
calling code.
PGHOST behaves the same as the host connection parameter.
...
"
So if you have PGHOST set to say localhost it would be added to:
psql -Upostgres
