If you need to restore a database on a remote server, you can connect psql to it using -h and -p options:.

If an SQL error occurs, the psql script continues to be executed; this is by default. If an error happens, you receive a partially restored database. To avoid this and complete the restoration, either fully successful or fully rolled back, set to restore a whole dump as a single transaction. To do it, use -1 option to psql:. It preserves role and tablespace definitions cluster-wide data and performs backups of each database in a given cluster.

Although each database will be internally consistent, snapshots of different databases may not be fully synchronized. Archived file formats are intended for transfer between architectures. Using the -j option, you can dramatically reduce the time to restore a large database to a server running on a multiprocessor machine. Each job represents one thread or one process; it uses a separate connection to the server and depends on the operating system. For example, this command will restore a database in four concurrent jobs:.

Standard Unix tools can be used to manage a directory format archive; for example, the gzip tool can be used to compress files in an uncompressed archive.

Before you try to change that password, make sure it's really what you want to do. What's the problem you're trying to solve here?

Are you attempting to install a database update or something else that's asking for the password for the postgres Windows user? Most likely you're just trying to log in to the database. For that, you use the unfortunately completely unrelated password stored in the database its self.
