MySQL vs PostgreSQL — Database Server Comparison
MySQL and PostgreSQL are the two dominant open-source relational databases. The choice depends on workload patterns, feature requirements, and ecosystem fit.
Quick Verdict
MySQL for read-heavy OLTP, simple replication, broadest web hosting tooling (LAMP, MariaDB). PostgreSQL for complex queries, JSON-native, GIS, transactional consistency.
Side-by-Side Spec Comparison
| Spec | MySQL | PostgreSQL |
|---|---|---|
| Type | OLTP-optimized | OLTP + OLAP hybrid |
| Replication | Native master-slave / Group Replication | Streaming + Logical |
| JSON Support | JSON type (5.7+) | JSONB (much faster) |
| Geographic Data (GIS) | Basic (Spatial) | PostGIS (industry-leading) |
| Window Functions | Yes (8.0+) | Yes (full) |
| CTE Support | Yes (8.0+) | Yes (full + recursive) |
| Stored Procedures | Yes (limited) | Yes (PL/pgSQL + Python + Perl) |
| Hosting / Cloud DB | Universal (AWS RDS, Aurora, Cloud SQL, all) | Universal (Aurora PG, Cloud SQL, etc.) |
| Hardware Sizing (per 100K QPS) | 16-cores, 128 GB RAM | 16-cores, 192 GB RAM |

Frequently Asked Questions
Which is faster: MySQL or PostgreSQL?
Depends on workload. MySQL is slightly faster for simple read-heavy OLTP. PostgreSQL is much faster for complex analytical queries and JSON workloads.
Should I pick MariaDB or MySQL?
MariaDB is a drop-in MySQL fork with some additional features. For new projects, both are equivalent. MariaDB is the default on most Linux distros now (RHEL 8+, Debian 11+).
Our Recommendation
PostgreSQL for new applications, complex queries, GIS, JSON. MySQL for existing LAMP stacks, simple read-heavy OLTP, or where MySQL-specific tooling matters.
