Make restore testing routine
Your goal
What you will be able to do
Plan a restore rehearsal with acceptance checks for data, applications, security, and elapsed time.
Why this matters at work
The practical reason
A restore that starts PostgreSQL may still contain the wrong data or fail application and security checks.
Learn
The idea in plain English
Restore into an isolated environment on a schedule. Record start and finish times, chosen recovery point, backup identifiers, WAL coverage, and every manual step.
Validate database consistency, important row counts, application queries, role access, extensions, and downstream integrations. Feed every failed or slow step back into the runbook.
Remember these points
- Restore in isolation and measure the complete elapsed time.
- Check data and application behaviour, not only server startup.
- Update the runbook from every rehearsal.

Capture a source database fingerprint
Create simple values that a restored database must match or explain.
SELECT
current_database() AS database_name,
count(*) AS account_count,
max(updated_at) AS latest_account_change
FROM training_accounts;The restored result should match the expected recovery point, which may deliberately precede the source's latest change.
Use several business checks rather than treating one count as proof of full consistency.
A database name, row count, and latest business timestamp that can be compared after restore.
