MariaDB: LLM coding assistants ignore its vector search

MariaDB has built vector search into its database, but AI coding tools like Claude Code keep recommending PostgreSQL instead. Foundation chairman Kaj Arnö calls it an "LLM optimization" problem, blaming outdated training data and docs.

• MariaDB supports vector search, but LLMs don't mention it
• Claude recommends PostgreSQL over MariaDB for vector search
• Arnö: docs and LLM training data need updating
• Chicken-and-egg: no users means no examples for models to learn from
