|
=============================================================================
|
|
|
|
-- Enable learning
|
|
SELECT ruvector_enable_learning('documents');

NEXT STEPS
|
|
=============================================================================
|
|
|
|
To use the learning module:
|
|
|
|
1. Build the extension:
|
|
cd /workspaces/ruvector/crates/ruvector-postgres
|
|
cargo pgrx install
|
|
|
|
2. Enable in PostgreSQL:
|
|
CREATE EXTENSION ruvector;
|
|
|
|
3. Enable learning for a table:
|
|
SELECT ruvector_enable_learning('my_table');
|
|
|
|
4. Start using - trajectories are recorded automatically!
