Stakeholder Basics

8 examples to get you started with Postgres stakeholder communication - 5 basic and 3 intermediate.

Prerequisites

SELECT pg_size_pretty(pg_database_size(current_database())) AS db_size;
SELECT pg_size_pretty(sum(pg_total_relation_size(relid))) FROM pg_stat_user_tables;

Monthly storage and query latency charts from Grafana or cloud console.
Business metrics: conversion rate, support tickets, active tenants.
Plain-language glossary: replica, backup, RPO, migration.

Basic Examples

1. Disk Growth to Business Risk

Technical signal	Business translation
PGDATA +18% MoM	Infrastructure budget overrun in 4 months
WAL retention spike	Checkout outage risk if disk fills
Index bloat 30%	Slower reports, longer month-end close

SELECT date_trunc('month', now()) AS month,
       pg_size_pretty(pg_database_size('app')) AS size;
-- Compare to last month export in spreadsheet

Attach dollar estimate: $/GB-month x projected TB.
Propose retention policy or archive, not only "run VACUUM."

2. Query Latency to Revenue

Checkout p95 rose from 120ms to 800ms (database slice 600ms).
Conversion dropped 0.4% = ~$220k/month modeled revenue.
Fix: index + pool tuning, 2 engineering days, no schema break.

SELECT query, mean_exec_time, calls
FROM pg_stat_statements
WHERE query LIKE '%orders%'
ORDER BY mean_exec_time * calls DESC
LIMIT 5;

Separate DB time from app time in APM traces.
Offer options with cost and time, not only problems.

3. Maintenance Window Framing

## Option A: Sunday 03:00 UTC window
- User impact: up to 45s write delay on billing API
- Benefit: validate FK on 80M payments (correctness)
- Skip risk: continued orphan rows in refunds
 
## Option B: Defer 6 weeks
- User impact: none now
- Risk: finance reconciliation errors accumulate

Product picks between risk and inconvenience.
DBA executes; does not own the trade-off alone.

4. Replication Lag as Freshness SLA

SELECT application_name,
       pg_size_pretty(pg_wal_lsn_diff(pg_current_wal_lsn(), replay_lsn)) AS lag_bytes
FROM pg_stat_replication;

Lag	Stakeholder message
< 1 MB	Real-time dashboards OK
500 MB	Analytics may miss last 10 minutes of sales
50 GB	Failover may lose more than DR promise

Align BI tools to delayed replica with banner when lag high.

5. Security and Compliance Language

"We need pgaudit on payments schema" →
"Regulators expect immutable payment access logs; gap is audit finding severity High."

Map extensions to control frameworks (SOC2, PCI).
Budget line for compliance is easier than "extension install."

Intermediate Examples

6. One-Page Executive Brief

# Database Health - July 2026
**Status:** Yellow (disk growth)
**User impact last month:** 12 min checkout degradation (Sev-2)
**Spend:** $48k/mo RDS + $6k observability
**Ask:** Approve Q3 archive project ($40k eng, saves $8k/mo storage)

Green/yellow/red status drives prioritization.
Always include explicit ask or "no action needed."

7. Roadmap Collision Negotiation

Product wants feature freeze blackout; platform needs PG 18 upgrade before EOL.

EOL: PostgreSQL 17 community support ends 2029; vendor extended 1 year.
Risk of defer: unpatched CVE exposure + hiring friction.
Proposal: upgrade week 2 after peak season; 4h planned budget spend.

Bring vendor EOL dates from Upgrade Calendar.
Quantify security risk in terms legal understands.

8. Post-Incident Stakeholder Summary

## Customer-safe summary (Sev-2)
Between 14:22-14:48 UTC some customers saw slow checkout.
No data was lost. Root cause: long database transaction from deploy.
Prevention: timeout policy + training (in progress).

No internal hostnames or query text.
Link to status page timeline for transparency.
