Specialist PostgreSQL Consultancy

Enterprise PostgreSQL, engineered for reliability.

Intelligres designs, migrates, and manages PostgreSQL on a proven FreeBSD and OpenZFS foundation — for stronger data integrity, faster recovery, and lower storage costs.

Why Intelligres

The advantages of doing it right, from the ground up.

We don't bolt reliability on after the fact. We build it into the foundation, where it belongs — so your team can focus on the application, not the database.

Data integrity

ZFS checksums every block and repairs silent corruption automatically — so the data you read is the data you wrote.

Fast recovery

Atomic snapshots and clones turn backups, point-in-time recovery, and test copies into operations measured in seconds.

Lower storage cost

Transparent compression typically shrinks PostgreSQL storage two- to three-fold, and can raise throughput at the same time.

A stable platform

FreeBSD's conservative releases and long support windows give you a predictable foundation that won't shift under you.

The Stack

A foundation chosen on purpose.

Three mature, open technologies, combined and tuned for one job: running your database reliably and efficiently.

Application Layer

PostgreSQL

The world's most capable open-source relational database — extensible, standards-driven, and trusted by organizations of every size.

Operating System

FreeBSD

A cohesive, well-documented operating system known for stability, predictable upgrades, and first-class native ZFS support.

Storage & Integrity

OpenZFS

A copy-on-write filesystem that checksums every block, snapshots instantly, compresses transparently, and heals corruption on its own.

THE FOUNDATION PostgreSQL, on bedrock. APPLICATION LAYER PostgreSQL queries · schema OPERATING SYSTEM FreeBSD a predictable base STORAGE & INTEGRITY OpenZFS copy-on-write · checksums · snapshots · compression where the advantage lives
01The Stack
DATA INTEGRITY Provably intact. Self-healing. READ BLOCK OpenZFS verify checksum · per block MIRROR A ✓ ✓ ✓ ✓ MIRROR B ✓ ✓ ✗ ✓ HEAL Every block is checksummed on write and verified on read. A failing copy is rebuilt from a known-good one — silently, automatically.
02Data Integrity
RECOVERY Backups & clones in seconds. LIVE DATABASE time 00:00 06:00 12:00 18:00 SNAPSHOT atomic · multi-TB WRITABLE CLONE full-size dev / staging copy, 0 extra bytes until changed Copy-on-write snapshots capture a consistent database instantly. Clones make any snapshot a writable copy — recovery without the fire drill.
03Snapshots & Recovery
STORAGE EFFICIENCY More database per dollar. RAW POSTGRES DATA 3.0 TB ON DISK · lz4 / zstd 1.1 TB ≈ 2.7× smaller — space you never buy Compression spans tables, indexes, and WAL — transparently. Fewer bytes means lower cost and, often, higher throughput.
04Storage Efficiency
WHY IT MATTERS The difference is the foundation. INHERITED DEFAULTS ENGINEERED FOUNDATION ✗ Silent corruption ✓ Checksummed & healed ✗ Restores in hours ✓ Recovery in seconds ✗ Opaque storage bills ✓ 2–3× compression ✗ Generic defaults ✓ Tuned to your workload ✗ Provider lock-in ✓ A foundation you own →

How We Work

A clear engagement, from first call to ongoing care.

We make the path predictable and low-risk, with defined milestones at every stage.

1

Assess

We review your current database, infrastructure, and goals, and identify the highest-impact opportunities.

2

Architect

We design a deployment tailored to your workload — pool layout, tuning, backups, and recovery built in.

3

Migrate

We move you over with a tested, low-downtime plan and verify data integrity end to end before cutover.

4

Operate

We monitor, tune, and support your database on an ongoing basis — or hand over a fully documented setup.

The Difference

How it compares to a generic setup.

Capability Typical managed / default setup Intelligres on FreeBSD + ZFS Engineered
Data integrity Silent corruption can go undetected Every block checksummed & self-healed
Backup & recovery Restores can take hours at scale Snapshots & clones in seconds
Storage efficiency Opaque, often rising costs 2–3× compression, transparent
Tuning One-size-fits-all defaults Tuned to your specific workload
Ownership Tied to a single provider Open stack you fully control
After moving our PostgreSQL estate onto the foundation Intelligres designed, our recovery testing went from a half-day exercise to a routine we run before lunch — and our storage bill went down.

Engage us for a single project or an ongoing partnership — whatever your database needs.

Architecture & Build

Greenfield PostgreSQL on FreeBSD and ZFS, designed around your workload from day one.

Migration

Move from Linux, a managed cloud database, or a legacy engine with a tested, low-downtime plan.

Performance Tuning

Resolve I/O, caching, and query bottlenecks across the full stack — from query plans to storage.

Backup & Disaster Recovery

Snapshot schedules, point-in-time recovery, and off-site replication, with restore drills that get run.

Health Audits

A focused review of an existing deployment, with prioritized, practical recommendations.

Managed Operations

Ongoing monitoring, upgrades, and capacity planning, with an expert on call when you need one.

Questions

Frequently asked questions.

Why FreeBSD and ZFS instead of Linux?
It's about the storage layer. ZFS has been a mature, first-class part of FreeBSD for well over a decade, with deep integration and predictable behavior. For a database, the integrity checking, instant snapshots, and transparent compression that ZFS provides translate directly into reliability and cost savings. We choose the stack on its technical merits for your use case — and we're happy to explain the trade-offs for your specific environment.
Is this production-ready, and who runs PostgreSQL this way?
Yes. PostgreSQL, FreeBSD, and OpenZFS are all mature, widely deployed technologies with long track records in demanding production environments. The combination is well-established among teams who take data integrity and operational efficiency seriously. We design every deployment to your reliability and compliance requirements.
Can you work with our cloud or on-premises environment?
We work across public cloud, private cloud, and on-premises hardware. Because the stack is open and portable, you're never locked into a single provider, and you can move between environments as your needs change. We'll recommend the right deployment model for your performance, cost, and sovereignty requirements.
How do you handle migrations with minimal downtime?
Every migration starts with an assessment and a tested plan. Depending on your tolerance for downtime, we use approaches ranging from scheduled maintenance windows to logical replication for near-zero-downtime cutovers. We verify data integrity end to end before, during, and after the move.
Will FreeBSD make it harder to hire or maintain?
In practice, day-to-day database administration looks very similar regardless of the underlying OS, and we provide thorough documentation and knowledge transfer. For teams that prefer it, our managed operations service means you don't need in-house FreeBSD expertise at all — we handle the platform so your engineers can focus on the application.
Do you offer ongoing support after a project ends?
Yes. Many clients keep us on a retainer for monitoring, upgrades, capacity planning, and on-call support. Others prefer a clean handover with documentation and training. Either way, we make sure you're never left without a clear path forward.
