Greptile Summary

This PR removes a duplicate ALTER TABLE "copilot_chats" ADD COLUMN "pinned" boolean DEFAULT false NOT NULL statement from migration 0208_modern_power_man.sql. The column was already added in the immediately preceding migration 0207_colorful_secret_warriors.sql, so the duplicate would cause a runtime error (column "pinned" of relation "copilot_chats" already exists) on any environment where both migrations run in sequence.

• Duplicate DDL removed: The pinned column addition that was mistakenly included in 0208 has been cleaned up; the canonical source remains 0207_colorful_secret_warriors.sql.
• No schema change: The final database schema is unchanged — only the erroneous second ADD COLUMN statement is dropped.

Confidence Score: 5/5

Safe to merge — removes a duplicate DDL statement that would have caused a migration failure on any environment running both 0207 and 0208 in sequence.

The change is a single-line deletion of a duplicate ADD COLUMN statement already present in the prior migration. The column definition in 0207 is identical, so no schema intent is lost, and the rest of 0208 is untouched.

No files require special attention.

Important Files Changed

Filename	Overview
packages/db/migrations/0208_modern_power_man.sql	Removes duplicate ADD COLUMN statement for copilot_chats.pinned; the column is correctly defined in 0207. The remaining content (workspace_file_folders table, indexes, FK constraints) is unaffected.
