📝 Walkthrough

Walkthrough

The PostgreSQL data writer now inserts relationships and attributes in chunks of 500 records. It uses squirrel-built INSERT statements, preserves relationship conflict handling, marshals attribute values with protojson, and skips empty collections.

Changes

PostgreSQL batch insert processing

Layer / File(s)	Summary
Chunked relationship and attribute inserts internal/storage/postgres/data_writer.go	batchInsertRelationships and batchInsertAttributes process slices in chunks of 500, return early for empty collections, build INSERT statements with squirrel, and queue one query per chunk. Relationship inserts retain the conflict clause. Attribute values continue to use protojson marshaling.
