PostgreSQL consultant and database design services

What PostgreSQL is and why it is a common default

PostgreSQL, usually called Postgres, is a free, open-source relational database that has been developed for decades and is known for being careful with data. It stores information in tables linked by relationships, enforces rules such as “every invoice must belong to a customer”, and keeps transactions all-or-nothing, so a payment is never half recorded.

It is also unusually flexible. JSONB columns let you store flexible, document-style data alongside regular tables. Built-in full-text search handles many search needs without a separate service. Extensions add more: PostGIS for maps and locations, pgvector for AI similarity search, and many others. Every major cloud offers managed Postgres, including Amazon RDS, Google Cloud SQL and Azure Database for PostgreSQL, and platforms like Supabase are built on it, so you are never locked into one vendor.

When PostgreSQL is the right choice, and when it is not

For most business software, Postgres is a safe, sensible default. Customers, orders, jobs, invoices, inventory and staff all relate to each other, and a relational database is built for exactly that, with reports written in plain SQL.

MySQL is a reasonable alternative and still powers a huge number of apps, especially in the PHP world. SQL Server makes sense if your company is deep in Microsoft tools and licensing. MongoDB can suit data whose shape varies a lot from record to record. For analytics on very large volumes, a data warehouse like BigQuery or Snowflake usually sits alongside Postgres rather than replacing it. And for a simple app with one user, a lightweight embedded database like SQLite can be enough.

What our database design services cover

• Designing a new database from your process: the tables, relationships and rules that keep data consistent.
• Moving data out of Excel, Google Sheets, Access, FileMaker or an old system, with cleanup of duplicates and gaps.
• Finding and fixing slow queries with proper indexes, better query plans and sensible caching.
• Row-level security, roles and audit logs, so each user or client only sees their own data.
• Backups and point-in-time recovery that are tested, not just switched on.
• Reporting views and read replicas so dashboards do not slow down the live app.
• Upgrades from old Postgres versions, and moves between hosts or clouds with minimal downtime.
• The web app, portal or API on top of the database, so the whole system is designed together.

PostgreSQL consultant, DBA or development company?

A freelance PostgreSQL consultant or database administrator (DBA) is a good choice for a focused job: a performance review, an upgrade or a replication setup. Look for someone who explains findings in plain English and leaves documentation behind.

A full-time DBA makes sense for companies with large, busy databases and many applications. Most small businesses do not have enough database work to fill that role, and a managed cloud database handles much of the routine upkeep.

A PostgreSQL development company like Zoti designs the database and the software that uses it as one piece, which avoids the most common problem: a database designed without knowing how the app will query it. Design, development, hosting and ongoing changes come with a dedicated project manager, on a monthly plan from $499/month.

How we design or fix a PostgreSQL database

1. Map the dataWe list every kind of record you keep, how they relate, and the questions you need the data to answer.
2. Model and reviewYou see a simple diagram of the tables and relationships and confirm it matches how the business works.
3. Measure before tuningFor existing databases, we find the slowest and most frequent queries before changing anything.
4. Migrate and checkData is moved in, cleaned and reconciled against the source, row counts and totals included.
5. Protect and maintainBackups, monitoring and access controls go live with the database, and we keep it healthy as data grows.
