Should I use PostgreSQL or MongoDB?

PostgreSQL for most applications — its JSONB type handles flexible schemas when needed, and relational integrity prevents data quality issues that document stores are prone to. MongoDB excels when your access patterns are genuinely document-oriented, you need horizontal write scaling, or you are working with highly variable nested data structures.

How do you handle database migrations safely in production?

We use versioned migration files committed to Git, applied in CI before deployment. For zero-downtime migrations we follow the expand/contract pattern: add columns as nullable, deploy code that handles both, backfill data, then add constraints in a second migration.

How do I know if my PostgreSQL queries are slow?

Enable pg_stat_statements to log query statistics. Use EXPLAIN (ANALYZE, BUFFERS) on slow queries to understand the execution plan. Identify sequential scans on large tables, missing indexes, and N+1 patterns from your ORM.

When should I consider sharding or Citus?

A well-optimised single PostgreSQL instance handles tens of millions of rows and thousands of queries per second. Consider Citus or application-level sharding only when you exceed these limits and read replicas no longer provide sufficient relief.

What is the best way to handle connection pooling in PostgreSQL?

PostgreSQL forks a process per connection — too many connections degrade performance. Use pgBouncer in transaction mode as a connection pooler, or RDS Proxy for serverless/Lambda deployments. Target a maximum of 100–200 concurrent PostgreSQL connections.

What We Build

Our PostgreSQL Development Services

PostgreSQL Schema Design

Normalised schema design with proper data types, constraints, and foreign keys — built for the queries your application will actually run.

PostgreSQL Performance Optimisation

Query analysis with EXPLAIN ANALYZE, index design, partial indexes, and schema refactoring to eliminate slow queries and N+1 patterns.

PostgreSQL Migration Services

Zero-downtime schema migrations using pgroll, flyway, or Liquibase — versioned, reversible, and safe for production deploys.

PostgreSQL High Availability Setup

AWS RDS Multi-AZ, streaming replication, pgBouncer connection pooling, and read replica configuration for high-traffic applications.

PostgreSQL Backup & Disaster Recovery

Automated backups, point-in-time recovery, and cross-region replica setup with tested restore runbooks.

PostgreSQL to Distributed Systems

Design and implementation of sharding strategies, Citus distributed PostgreSQL, or migration paths when a single PostgreSQL instance is no longer sufficient.

Technology Advantage

Why PostgreSQL for Your Business?

PostgreSQL is our default database for production applications. Its ACID compliance, support for JSON, full-text search, array types, and window functions make it versatile enough to replace many specialised databases. The managed ecosystem (AWS RDS, Supabase, Neon) removes operational burden. At Bluejay, we design PostgreSQL schemas for long-term maintainability — proper normalisation, index design, partitioning, and migration strategies from day one.

Full ACID Compliance

PostgreSQL's strict ACID guarantees mean transactions either fully commit or fully roll back — your data is always consistent, even after crashes or failures.

Advanced Data Types

JSONB, arrays, ranges, hstore, PostGIS (geospatial), and full-text search are built in — reducing the need for separate specialised databases.

Sophisticated Query Planner

PostgreSQL's query planner uses statistics-based cost estimation to choose optimal execution plans — including parallel query, merge joins, and partition pruning.

Powerful Indexing Options

B-tree, GIN (for JSONB and arrays), GiST (for geospatial), partial, and expression indexes give you the tools to optimise any access pattern.

Open Source with No Licensing Cost

PostgreSQL is completely free and open source under the PostgreSQL License. There are no per-core fees, no enterprise tiers, and no vendor lock-in.

Managed Service Ecosystem

AWS RDS, Aurora, Supabase, and Neon offer managed PostgreSQL with automated backups, patching, and scaling — removing nearly all operational burden.

How We Work

Our Processes

We deliver a structured process for seamless project execution. From understanding your requirements to delivering the final solution, we ensure proactive technology services based on your business needs.

Sprint Planning

We break the project into focused sprints with clearly defined goals, priorities, and deliverables, keeping the team aligned and progress visible at all times.

Design & Development

Each sprint delivers working software from UI design to backend logic, with continuous collaboration and daily standups to keep momentum high.

QA & Testing

Every sprint output goes through rigorous quality assurance, automated testing, and code review to ensure reliability, performance, and security.

Review & Iteration

At the end of each sprint, we demo progress to stakeholders, collect feedback, and refine the roadmap to ensure the final product perfectly fits your needs.

Release & Optimization

Once validated, we deploy to production and monitor closely. Post-launch optimizations ensure your product performs at its best from the first day live.
