📝 Walkthrough

Walkthrough

PostgreSQL relationship and attribute writers now build chunked squirrel INSERT queries. Each chunk contains up to 500 records. Empty collections return immediately.

Changes

PostgreSQL insert batching

Layer / File(s)	Summary
Chunk relationship and attribute inserts internal/storage/postgres/data_writer.go	batchInsertRelationships and batchInsertAttributes now queue one squirrel INSERT per 500 records. Empty inputs return early. Relationship inserts retain the conflict constraint handling, and attribute values are marshaled to JSON.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 4fcd5

PostgreSQL relationship and attribute writes now batch inserts in chunks while preserving conflict handling. No merge-blocking risk remains.
