Changelog

0.1.3

Added: data_field mode :map - aggregates a join into a JSON object keyed by key_column with values from value_column. The key and value may come from different tables in the join chain. Example output: {"en": "English", "fr": "French"}.

Added: Configuration validation for data fields. Invalid :object_array column references and aggregate mismatches are now caught when reading the configuration and reported before they can surface as database errors during creation or merging.
Fixed: create_document_table now rolls back on failure. If creation or backfilling fails, the document table and its maintenance infrastructure (triggers, deltas table, and functions) are removed, so a failed call leaves no partial state and can be safely retried after the cause is fixed.

Added macro Collect.Schema.default_collect_fields/0 to simplify Ecto.Schema configuration.
Added Search documentation.

Initial implementation.
