Understanding how PostgreSQL works begins with its architecture. PostgreSQL uses a client‑server model: clients send SQL commands, and the server’s backend processes execute them. Data is stored in pages inside files on disk, organised into tablespaces. PostgreSQL implements Multiversion Concurrency Control (MVCC), so readers never block writers; instead, each transaction sees a snapshot of the data. Write‑ahead logging (WAL) ensures durability: every change is recorded in a log before it is applied to the database.
PGEE builds on this architecture by adding adaptive query optimisation, which analyses past execution plans to improve future performance, and automatic table bloat removal via pg_squeeze . Its integrated scheduling and monitoring tools make it easier to automate routine tasks and detect anomalies. PGEE’s encryption features ensure that MVCC snapshots and WAL files are always protected .
How CYBERTEC PGEE can help: PGEE enhances PostgreSQL’s architecture with enterprise‑grade features that meet stringent regulatory requirements. Transparent encryption, data masking and code encryption protect sensitive data\ , while performance improvements reduce latency and boost throughput . Worlber’s team can show you how PGEE works under the hood and migrate your applications seamlessly.
