PrismBase Product: DB Optimizer
Know exactly what's slowing your Postgres & Supabase
A 48-hour read-only database audit for B2B SaaS teams. PrismBase proprietary tooling surfaces slow queries, missing indexes, and connection issues, delivered as a prioritized report your engineers can act on immediately.
Read-only access · 48-hour turnaround · Full remediation from $8k
The Problem
Your database is the bottleneck you can't see
As B2B SaaS scales, Postgres performance degrades quietly, an unindexed filter here, connection pool exhaustion during deploys there. APM tools show slow endpoints; they rarely show which query or index is responsible.
Hiring a DBA is overkill. Generic checklists miss your schema. DB Optimizer gives you a senior-engineer-grade audit in 48 hours, scoped to your actual production workload.
Postgres & Supabase native
Built for the stack B2B SaaS actually runs, not generic database theory.
48-hour delivery
Fixed window, fixed deliverable. No open-ended consulting retainer to start.
Read-only, always
We analyze. We don't migrate, mutate, or experiment on your production data.
How It Works
Four steps to a clearer database
01
Secure read-only access
You grant read-only credentials to your Postgres or Supabase instance. We never write to your database, run migrations, or modify schema.
02
Automated + expert analysis
PrismBase proprietary tooling ingests query stats, EXPLAIN plans, index usage, and connection metrics. Senior engineers validate and prioritize findings.
03
Prioritized report delivery
Within 48 hours you receive a severity-ranked report: slow queries, missing indexes, pool issues, and schema risks, with concrete remediation steps.
04
Engineering walkthrough
A 30-minute call with your team to walk through critical findings, answer questions, and scope optional implementation support if you want hands-on help.
Security
Built for teams who can't take risks
Read-only credentials only
No INSERT, UPDATE, DELETE, or DDL permissions. Revoke access immediately after the audit window.
No data exfiltration
We analyze metadata, query plans, and schema statistics, not row-level customer data.
Time-bounded access
Credentials are used only during the 48-hour audit period and documented in our engagement letter.
NDA available
Standard mutual NDA on request. Findings stay confidential to your organization.
Sample Report
What you'll receive
Redacted findings from a representative B2B SaaS audit. Your report is tailored to your schema, query patterns, and infrastructure.
48-hour read-only audit
B2B SaaS: Series B (redacted)
Supabase Postgres 15: production
We identified 12 actionable findings across query performance, indexing, and connection management. Three are critical, addressing them is projected to reduce p95 API latency on core endpoints.
Query Performance
Slow Query
Unindexed filter on orders.user_id + created_at
SELECT on orders table scans ~2.1M rows per request. Observed avg 840ms, p95 2.3s on /api/v2/orders endpoint.
Recommendation: Add composite index (user_id, created_at DESC). Estimated 95%+ reduction in scan time.
N+1 Pattern
Eager loading missing on subscription → plan join
ORM generates 47 sequential queries per dashboard load. Connection pool saturation during peak hours.
Recommendation: Refactor to single JOIN or batch loader. Consider materialized view for dashboard aggregates.
Query Plan
Sequential scan on events.metadata JSONB filter
GIN index exists but query uses jsonb ->> cast preventing index usage.
Recommendation: Rewrite filter to use @> containment operator or add expression index on extracted key.
Indexing & Schema
Missing Index
Foreign key on invoice_items.product_id unindexed
DELETE cascades on products table trigger sequential scans. Lock wait events observed during catalog updates.
Recommendation: Add index on invoice_items(product_id). Verify FK constraint behavior post-deploy.
Unused Index
6 indexes with zero scans in 30-day window
idx_users_legacy_token, idx_events_old_source, and 4 others consume ~340MB write overhead.
Recommendation: Drop after confirming no ad-hoc reporting dependencies. Reclaim storage and reduce write amplification.
Schema Drift
Nullable columns with CHECK constraints disabled
Three tables have NOT NULL constraints commented out in migration history but enforced only at app failure.
Recommendation: Re-enable constraints in staged migration. Align ORM models with database truth.
Connection & Resource Management
Pool Config
Supabase pooler max connections exceeded during deploys
PgBouncer transaction mode with 60 client connections vs 15 pool size. Deploy restarts spike idle-in-transaction sessions.
Recommendation: Increase pool size or reduce per-instance connection limit. Add connection timeout and statement_timeout defaults.
Vacuum
Autovacuum lag on high-churn events table
Dead tuple ratio at 18%. Last autovacuum 4 days ago despite 200K+ daily inserts.
Recommendation: Tune autovacuum_vacuum_scale_factor for events. Schedule manual VACUUM ANALYZE during low-traffic window.

FAQ
Common questions
What databases do you support?
Postgres 12+ and Supabase-hosted Postgres. If you run RDS, Cloud SQL, Neon, or self-hosted Postgres, we support those too, as long as we can connect read-only.
Will this impact production performance?
Analysis uses standard catalog queries and pg_stat views. We schedule heavy EXPLAIN work during off-peak windows when possible. No schema changes are made.
What if we need help implementing fixes?
The audit is standalone. Full remediation engagements start at $8k and include pairing with your team, migration scripts, and before/after benchmarking.
Is DB Optimizer open source?
DB Optimizer runs on PrismBase proprietary tooling built for client engagements. There is no public repository; we deliver findings as a managed audit service.
How is founding pricing different?
Founding clients ($2,500) receive the same 48-hour audit deliverable. We cap founding slots to refine the product with early B2B SaaS teams on Postgres/Supabase.
