Understand Oracle-compatible Postgres before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is Advanced Server?
EDB's Oracle-compatible enterprise Postgres — running Oracle's PL/SQL, syntax and features on Postgres, so Oracle apps migrate with minimal rewriting.
The leading, most-proven path off Oracle.
Staying on Oracle vs migrating to compatible Postgres — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Stay on Oracle (or full rewrite) | EDB Advanced Server (compatible) |
|---|---|---|
| Oracle licensing | Expensive, growing | Cut dramatically |
| The trap | PL/SQL & Oracle features | Run on Postgres (compat) |
| Migration effort | Huge (plain Postgres) | Far smaller (Advanced Server) |
| The move | All-or-nothing leap | Assess then migrate, scoped |
| After migration | New lock-in? | Open Postgres, runs anywhere |
| HA | Oracle RAC (pricey) | PGD active-active |
| Support | Oracle | EDB, accountable |
| The destination | Proprietary | Industry-standard Postgres |
The most-proven Oracle escape — no migration is zero-effort; assessment and testing are essential.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Oracle Compatibility Layer
A high degree of Oracle compatibility — PL/SQL, much of Oracle's syntax, packages, functions and behaviours — so Oracle apps run on Postgres with minimal rewriting.
Enterprise Postgres
Enterprise-grade Postgres with added security, performance and manageability features — the robust database beneath the compatibility.
Migration Tooling
Tooling and methodology to assess Oracle workloads for compatibility and migrate them — turning an intimidating move into a scoped project.
HA Foundation
The foundation for EDB Postgres Distributed (PGD) — so migrated workloads can reach active-active, up-to-99.999% availability.
Open & Supported
True open Postgres, run anywhere, with EDB enterprise support — freedom from Oracle without a new lock-in.
One enterprise Postgres with an Oracle compatibility layer — PL/SQL carried over, with a path to distributed HA.
Twelve capabilities. Compatible, migrate, save.
EDB Postgres Advanced Server runs your Oracle PL/SQL and features on Postgres — so you escape Oracle's licensing without rewriting everything.
PL/SQL Compatibility
Runs Oracle PL/SQL — the stored procedures, packages and code that make Oracle apps hard to move, kept working.
Oracle Syntax & Features
Supports much of Oracle's SQL syntax, functions, packages and behaviours — minimising application rewrites.
High Compatibility
A high degree of Oracle compatibility — far more of your Oracle workload runs unchanged than on plain Postgres.
Migration Assessment
Assess Oracle workloads for compatibility — know what moves cleanly and what needs attention, before you commit.
Migration Tooling
Tooling and methodology to migrate schema, data and code from Oracle to Postgres — a scoped project, not a leap of faith.
Licensing Savings
Cut Oracle licensing cost dramatically by moving to EDB Postgres — usually the whole business case.
Enterprise Security
Added security features on Postgres — the protection enterprise and migrated workloads need.
Performance Features
Enterprise performance and manageability features — Postgres tuned for demanding, migrated workloads.
HA Foundation (PGD)
The foundation for active-active PGD — migrated workloads can reach up to 99.999% availability.
Open & Portable
True open Postgres — run anywhere, no new lock-in. Freedom from Oracle, not a swap of one cage for another.
EDB Enterprise Support
Enterprise support and accountability — the safety net for migrating and running mission-critical workloads.
On the Industry Standard
Built on Postgres — the open database the industry is converging on. A future-proof destination.

Book a guided demo →It’s the apps that trap you. Compatibility frees them.
Here’s what genuinely sets EDB Postgres Advanced Server apart from the alternatives.
It's the apps, not the data, that trap you in Oracle
Oracle lock-in lives in the applications: years of PL/SQL procedures and Oracle-specific features that are costly and risky to rewrite. EDB Postgres Advanced Server runs Oracle’s PL/SQL, syntax, packages and features, so those apps move to Postgres with far less rewriting — the leading Oracle-escape path.
The business case writes itself: licensing
Oracle licensing is expensive and complex, a recurring cost that grows with usage and audits. Moving Oracle-style workloads to EDB Postgres can cut it dramatically, and for most organisations that saving is the whole business case. EDB Postgres Advanced Server is the most-proven way to capture it.
Compatibility means less rewriting than plain Postgres
Community PostgreSQL doesn’t understand Oracle’s PL/SQL and many Oracle-specific features, so migrating to it means rewriting far more code. EDB Postgres Advanced Server supports PL/SQL, syntax, packages and behaviours, so much more runs unchanged — a scoped migration rather than a massive rewrite.
Assess first, then migrate with confidence
A responsible Oracle migration starts with assessment: what moves cleanly and what needs attention. EDB provides tooling and methodology to assess compatibility, then migrate schema, data and code, turning an all-or-nothing move into a scoped project with known effort.
Freedom without a new cage
Leaving Oracle for another proprietary database or a single cloud isn’t freedom. EDB Postgres Advanced Server is open Postgres that runs on-prem, on any cloud or hybrid, with no new lock-in, optional active-active PGD high availability, and enterprise support from EDB.
The honest positioning
EDB Postgres Advanced Server is the most-proven, most Oracle-compatible path off Oracle. Alternatives: plain PostgreSQL (more rewriting), AWS/Azure/Google managed Postgres (cloud-locked) or staying on Oracle (expensive). No migration is zero-effort — assessment and testing are essential.

Quick poll — what’s driving your evaluation?
Talk to an advisor“Advanced Server ran our PL/SQL-heavy apps on Postgres with far less rewriting, and cut database licensing cost dramatically.”
“Years of PL/SQL trapped us, not the data. Oracle compatibility kept most of it working; without it, leaving wasn’t feasible.”
“We assessed first — what moved cleanly, what needed attention — then migrated as a scoped project, not a leap of faith.”
“Open Postgres that runs anywhere, with EDB enterprise support: we escaped Oracle’s licensing and lock-in without a new cage.”
“The licensing saving funded the whole migration and more. At a fraction of the Oracle cost, the numbers decided it.”
“Plain Postgres would have meant far more rewriting; Advanced Server’s compatibility made the migration smaller and safer.”
“No migration is effortless: some Oracle features needed attention and testing was essential. EDB was still the right path.”
“It's the foundation for PGD too — our migrated workloads reached active-active HA. Freedom from Oracle AND five-nines availability.”

EDB Advanced Server vs the field
Staying on Oracle, plain Postgres and cloud Postgres — honest lanes; the edge is high compatibility plus savings plus openness.
| Dimension | EDB Adv Server | Stay on Oracle | Plain PostgreSQL | AWS Aurora Postgres | Other DB migration |
|---|---|---|---|---|---|
| Oracle compatibility | High (PL/SQL, syntax) | Native (it IS Oracle) | Low | Low (Postgres) | None |
| Licensing cost | Dramatically lower | Very high | Free (community) | Cloud pricing | Varies |
| Openness / no lock-in | Open, runs anywhere | Locked | Open | Cloud-locked | Depends |
| Enterprise support | EDB, accountable | Oracle | Community | AWS | Per vendor |
| Best fit | Orgs escaping Oracle licensing with minimal rewrite | Deeply Oracle-committed | Greenfield / non-Oracle | Single-cloud AWS shops | Full-rewrite tolerant |

Honest fit signals — because the fastest way to lose your trust is to pretend one product wins every scenario.

Drag the sliders (count Oracle database instances/cores scaled here as instances; IT-hour cost as a proxy for licensing rate). Estimates model the recurring Oracle-licensing cost, with ~55% representative of the saving from migrating compatible workloads to EDB Postgres — the exact saving depends on your Oracle edition and usage; the migration cost is one-off against a recurring saving.
