PostgreSQL Agency

Two platforms that look similar rarely call for the same data schema. The budget depends on the number of tables, the integrity rules to set and the volume of data expected: a schema for a platform with a few entities costs markedly less than a database linking dozens of tables together with cross-referenced constraints. We first frame your business rules with you before pricing anything at all. Every PostgreSQL project is then priced on quotation, with a precise breakdown of the schema chosen, sent within 24 hours of that first scoping.

A database for a platform with limited business rules is designed in 21 to 30 days once scoping is complete. A broader platform, with several modules and cross-referenced constraints between many tables, calls for closer to 21 to 60 days, and up to 60 days for a scope extended to several distinct user profiles. The schema is validated before the interfaces are developed, to avoid having to redo everything after the fact. This lead time includes load testing before any opening to end users.

PostgreSQL is the obvious choice for a custom business platform, where strict integrity rules have to link several types of data together with no possible gap. MySQL remains preferable as soon as the project rests on WordPress or WooCommerce, the database those platforms natively expect. We never choose a database as a matter of principle: the nature of the project, custom-built or built on an existing system, settles the question from the scoping stage. A platform that starts simple can in fact migrate to PostgreSQL if its business rules become more complex later.

Yes, we regularly work on PostgreSQL databases left by another team or built on Supabase. The audit covers the integrity constraints actually set, the data access rules and the slowest queries identified in the server logs. This step separates what can stay as it is from what has to be strengthened before adding a new module. You receive this report before any decision to develop the platform. This diagnosis commits you to nothing until you have validated what happens next.

Yes, in the form of an optional annual package, whose content depends on the criticality of your platform: monitoring of slow queries, regular backups and adjustments to the schema as new modules are added. A database centralising sensitive business rules deserves regular follow-up, because a badly set constraint can let an inconsistency through for months. This package remains optional: the database belongs to you from delivery onwards, whatever you choose afterwards.

Yes, without reservation. You receive full access to your database, with documentation of the schema and the constraints set, including when the project goes through Supabase, where the access keys remain under your account from the outset. For a business platform built over several years, this independence matters particularly, since it lets you entrust the rest of the project to another technical team if you wish, without depending on us in the long run. No technical access is retained on our side once the project is delivered.

Indirectly, yes: a platform whose queries stay fast despite complex business rules displays pages more quickly, a criterion Google takes into account in its ranking. On a platform with a lot of content generated from the database, a badly thought-out schema slows down every page that queries it. We check this point from the schema design stage, even before the platform hosts its first real content. A slow platform also loses visibility with search engines, well before any content problem.
