SQL Assets

001_agent_data_schema.sql creates the PostgreSQL-backed storage layer for:

• sessions
• memory_store
• memory_store_working
• conversation_history
• system_prompts

The migration also provisions:

• required extensions when available
• hash partitions for session and memory data
• hash plus monthly range sub-partitions for conversation history
• vector, trigram, GIN, and B-tree indexes aligned to the retrieval plan
• helper functions for updated_at maintenance and rolling monthly partition creation

Run it with a PostgreSQL role that can create extensions and schema objects if you want the full feature set.
