# Postgres vs Oracle

**[Tinybird](https://daily.dev/sources/tinybird)** · 7 min read · 0 upvotes · 0 comments

## Summary

A technical comparison of Postgres and Oracle Database covering licensing costs, extension ecosystems, SQL dialect differences, HA architecture, and partitioning maturity. Both databases share the same OLTP ceiling for analytical workloads — once tables grow large, aggregation queries degrade performance. The recommended architectural pattern for both is CDC-based streaming to a columnar OLAP layer (ClickHouse/Tinybird), keeping the operational database for transactions. Includes a practical Oracle-to-Postgres SQL translation table and notes on PL/SQL migration challenges.
