Identify the artifact
PostgreSQL distinguishes plain SQL output from archive formats used with its restoration tooling. A filename extension is a hint, not sufficient proof. Keep the producing tool, version, options and documented format in the backup record. Compression and encryption are additional layers, not substitutes for knowing the underlying format.
Plan for selective recovery
Decide whether a future operator needs a whole database or selected objects. Check the official tooling for the chosen archive format and the constraints of your database. Do not assume a convenient UI option supports every selective restore, ownership mapping or extension you use.
Check compatibility early
Run a controlled rehearsal against the intended target version and environment. Capture warnings and missing dependencies rather than hiding them behind a successful process exit. Restore instructions should identify where role, ownership and application-specific checks are handled.
A portable handoff record
A useful record says which artifact was tested, what isolated target received it and what evidence passed. It should not contain passwords, connection strings with credentials or a production restore command ready to paste blindly. Keep secrets in the organization’s approved secret-management mechanism.
Separate packaging from restoration
Fictional handoff: an operator receives an encrypted, compressed archive and assumes the outer filename identifies the restore command. Instead, first consult the saved producing-tool and format record, then follow the approved decryption and unpacking procedure in an isolated environment. Keep each layer explicit: encryption, compression and database archive format. The PostgreSQL documentation explains the underlying restore tooling; it does not validate an unknown third-party archive. If the format record is missing, resolve that uncertainty before issuing commands that could modify a database.
