-- 014_notes.sql — Notes table with full-text search
|
|
--
|
|
-- Notes are user-scoped persistent documents. The LLM can create, search,
|
|
-- and update them via built-in tools (note_create, note_search, etc.).
|
|
-- Full-text search uses PostgreSQL tsvector — zero additional infrastructure.
|
|
--
|
|
-- DROP first: if a previous deployment created an incomplete version of
|
|
-- this table (e.g. missing search_vector), IF NOT EXISTS would skip and
|
|
-- the indexes/trigger would fail. Safe because 014 was never recorded
|
|
-- in schema_migrations — any existing data is from a failed attempt.
