Option 1: Switch to a Trusted User Authentication Method

1. Open the PostgreSQL configuration file (postgresql.conf) on your local machine.
2. Locate the line that begins with #listen_addresses and remove the # to uncomment the line.
3. Change the value after listen_addresses to '*' to allow connections from any IP address.
4. Save the changes and exit the file.
5. Open the pg_hba.conf file, which controls client authentication.
6. Find the line that corresponds to the "admin" user and change the authentication method from peer to trust.
7. Save the changes and exit the file.
8. Restart the PostgreSQL service for the changes to take effect.
9. Retry the pg_restore command.

Option 2: Use a Different Authentication Method

1. Open the pg_hba.conf file.
2. Find the line that corresponds to the "admin" user and change the authentication method from peer to a different method such as md5 or password.
3. Save the changes and exit the file.
4. Restart the PostgreSQL service for the changes to take effect.
5. Retry the pg_restore command.

Note: Using trust or a non-secure authentication method (like md5 or password) is not recommended for production systems. It is advisable to use stronger authentication methods and provide proper credentials for database access.

Remember to exercise caution when modifying PostgreSQL configuration files, as incorrect changes can lead to security vulnerabilities or service disruptions.
