DESCRIPTION:Oracle is known for Oracle Database\, one of the most widely us
 ed proprietary database. So why is Oracle offering a managed PostgreSQL se
 rvice?\n\nThis session starts with that unexpected question and uses it as
  a lens to explore a broader shift in modern application architecture: ent
 erprises increasingly want the openness\, ecosystem\, and developer famili
 arity of PostgreSQL\, while also needing cloud-native operations\, high av
 ailability\, scalable infrastructure\, and integration with AI services.\n
 \nOCI Database with PostgreSQL is Oracle Cloud Infrastructure’s fully ma
 naged PostgreSQL service. Rather than positioning it as a replacement for 
 self-managed PostgreSQL or as a proprietary database story\, this talk exa
 mines the technical design choices behind running PostgreSQL as a managed 
 service: separation of compute and storage\, database-optimized shared sto
 rage\, automated backup and restore\, read scaling through replicas\, high
  availability with fast failover\, and operational integration with cloud 
 monitoring and security services.\n\nA key focus will be PostgreSQL’s ex
 tension ecosystem and why it matters for AI-era applications. We will look
  at extensions such as pgvector for vector search\, PostGIS for geospatial
  workloads\, pglogical for replication scenarios\, and other operational e
 xtensions that make PostgreSQL more than a traditional relational database
 . In particular\, the session will explain how PostgreSQL can act as a vec
 tor store for retrieval-augmented generation (RAG)\, hybrid search\, and s
 emantic search use cases\, while remaining part of a familiar SQL-based ap
 plication architecture.\n\nThe talk will also cover practical architecture
  patterns: using PostgreSQL with object storage\, streaming\, AI services\
 , application containers\, and search/cache services to build modern appli
 cations on open source components. The goal is not to present a product pi
 tch\, but to discuss what it means to operate an open source database as a
 n enterprise-grade managed service\, and where the trade-offs appear betwe
 en openness\, operational control\, performance\, resilience\, and cloud i
 ntegration.\n\nAttendees will leave with a clearer understanding of how ma
 naged PostgreSQL services are evolving\, how PostgreSQL fits into AI appli
 cation architectures\, and why even a company strongly associated with Ora
 cle Database sees PostgreSQL as an important part of the modern open sourc
 e data platform.
