v0.3.0

Added

• bee.definition(p_table, p_column): the current definition of a derived column (version, backend, model, prompt, output schema, backend config, config) without the queue counters of bee.columns, cheap enough to read on every request.

Changed

• Results of vector and halfvec columns no longer copy the vector into bee.result.value, which stays null: the column holds the value, and the copy took ten times its space as jsonb.

Fixed

• A deleted row kept a current result forever, so its lineage was never pruned, and a row deleted and inserted again with the same key and sources was never computed. Deleting a row, or truncating the table, now retires its current result to the superseded lineage and drops its live jobs.

Upgrading

• Extension version 0.16 (0016_forget_deleted_rows.sql): run pgbee install, or ALTER EXTENSION pgbee UPDATE. The update installs two triggers on every table with a derived column (bee_forget_<column>, bee_forget_all_<column>), retires the current results of rows that no longer exist with one anti-join per table, and clears the vectors stored in the lineage: on large tables and lineages it takes a while and locks the rows it updates. The worker contract does not change.
