Answer
Use partitioning, tuned WAL settings, more autovacuum workers, and unlogged tables. Scaling writes often requires sharding or logical replication.
Quick Answer
High write throughput in PostgreSQL: use COPY instead of INSERT for bulk loads (10-100x faster). Batch inserts with multi-row VALUES. Disable synchronous_commit for non-critical writes. Use unlogged tables for temp data (no WAL, much faster). Partition tables to distribute writes. Tune autovacuum to keep up with deletes/updates. Use connection pooling (PgBouncer) to reduce connection overhead. SSDs dramatically improve write throughput.
