# +-- Restoration can be performed by using psql or pg_restore.
# | Here are two examples:
# |
# | a) If the backup is plain text:
# |
# | Firstly gunzip your backup file (if it was gzipped).
# |
# | gunzip backup_file.gz
# | psql -U postgres database < backup_file
# |
# | b) If the backup is not plain text:
# |
# | Firstly gunzip your backup file (if it was gzipped).
# |
# | gunzip backup_file
# | pg_restore -d database -F {c|t} backup_file
# |
# | Note: {c|t} is the format the database was backed up as.
# |
# | pg_restore -d database -F t backup_file_tar
# |
