pg_restore: Clean database objects before creating them.
$ pg_restore --clean -d ${db_name} ${archive_file-dump}

The command pg_restore
is used to restore a PostgreSQL database from backup files created by pg_dump
. Let's break down the command and explain each part:
pg_restore
: This is the command itself, used for restoring a database.--clean
: This flag tellspg_restore
to drop the existing database objects before restoring. It ensures a clean state before restoring the backup.-d ${db_name}
: This specifies the name of the database where the backup will be restored. Replace${db_name}
with the actual name of your target database.${archive_file-dump}
: This is the path to the backup file that will be used for restoration. Replace${archive_file-dump}
with the actual path to your backup file.
In summary, this command will restore the specified PostgreSQL backup file into a specified database, and before restoring, it will drop any existing database objects to create a clean state.
