What we fix

PGFlare's PostgreSQL performance consulting covers the full spectrum of RDS performance issues that drain engineer time and inflate AWS bills. Every engagement starts with your actual workload data — not generic best-practice checklists.

Slow query identification and root cause analysis using pg_stat_statements
Missing index detection and redundant index removal to reduce write amplification
Autovacuum lag diagnosis and table-level parameter reconfiguration
Table bloat and dead tuple accumulation remediation
Connection pool sizing and PgBouncer configuration
Lock contention and deadlock pattern analysis
RDS parameter group review against PostgreSQL 16.9+ planner improvements
Transaction ID wraparound risk assessment

Before and after

These are real patterns we see on first engagement. Within a single session, teams typically move from firefighting to understanding — and from understanding to fixed.

Before PGFlare

Queries taking 8–30 seconds. Engineers unsure which queries to fix first. Autovacuum running but tables growing unbounded. Incidents every 2–3 weeks disrupting standups.

After PGFlare

Top 5 queries optimised: response times down 60–90%. Autovacuum reconfigured per-table. Bloat cleared. Incident frequency at zero for 8+ weeks post-remediation.

Our methodology

Every PostgreSQL performance consulting engagement follows a structured diagnostic-to-remediation process. We do not guess — every recommendation is backed by data from your instance.

Read-only diagnostic access

You grant a scoped IAM read-only role. We connect to pg_stat_* views — no application data, no schema changes. IAM setup guide →

Workload baseline analysis

We analyse query execution patterns, index usage, autovacuum history, lock graphs, and connection pool saturation against your actual workload — not synthetic benchmarks.

Prioritised remediation plan

You receive a written report ranking every issue by impact, with specific SQL or parameter changes to fix each one. Delivered same day, before end of session.

Active implementation (Remediation+ only)

On Remediation+ sessions we implement every fix with your explicit approval at each step. All index operations use CONCURRENTLY. Zero downtime, zero surprises.

Post-session monitoring

Remediation+ includes a 30-day follow-up check to confirm improvements held and surface any secondary issues that emerge after the primary bottlenecks are removed.
