BEST FOR

Who this fits

PostgreSQL is recommended when: COMPLEX / WRITE-HEAVY / EXTENSIBLE. Richer types, better query optimizer, extensibility (PostGIS, custom functions).

LESS SUITABLE FOR

Who should look elsewhere

Less suitable if you match: SIMPLE / READ-HEAVY WEB — in that case MySQL may be a better fit.

KEY CAPABILITIES

• Richer types (arrays, JSONB, XML, custom types); extensible via PostGIS (geospatial) and many extensions. • Excels at complex queries and write-heavy workloads; stronger query optimizer and index types. • Requires manual vacuuming for dead tuples and index bloat management. • Logical replication, improving but more complex to configure.
