A PostgreSQL driver for Kotlin that speaks Wire Protocol v3.2 directly: types read from your catalog, COPY, LISTEN/NOTIFY, large objects and TLS. Blocking by design and pin-free on virtual threads. Requires PostgreSQL 18 or newer.

SQL-first data access on the Octavius PostgreSQL driver: session scoping, thread-bound transactions, query builders and transaction plans.

Spring Boot autoconfiguration for the Octavius PostgreSQL driver: OctaviusTemplate, a transaction manager, DataSource wiring and exception translation. Requires Spring Boot 4.x.

Schema migrations for PostgreSQL on the Octavius driver: versioned and repeatable, in SQL or in Kotlin, with checksums, an advisory lock and a history table it keeps itself.
