📝 Walkthrough

Walkthrough

The PostgreSQL writer now uses squirrel to build batched INSERT statements for relationships and attributes. Each method processes up to 500 rows per statement and returns immediately when its input is empty.

Changes

PostgreSQL batch inserts

Layer / File(s)	Summary
Chunked relationship and attribute inserts internal/storage/postgres/data_writer.go	batchInsertRelationships and batchInsertAttributes build squirrel INSERT statements in batches of 500. Relationship inserts preserve the conflict- ignore suffix. Empty inputs return without queueing statements.

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

Merge Risk: ⚪ Minimal · up to d74b5

The change is localized to PostgreSQL batch writes, adding chunked inserts and empty-input handling; no actionable merge-blocking risk remains after normal checks and review.
