PostgreSQL requires GROUP BY for all non-aggregated columns when using aggregate functions. Added group_by(pitcher, game) to the StratPlay query that calculates pitcher innings in the /decisions/rest endpoint.
- Add db_helpers.py with cross-database upsert functions for SQLite/PostgreSQL - Replace 12 on_conflict_replace() calls with PostgreSQL-compatible upserts - Add unique indexes: StratPlay(game, play_num), Decision(game, pitcher) - Add max_length to Team model fields (abbrev, sname, lname) - Fix boolean comparison in teams.py (== 0/1 to == False/True) - Create migrate_to_postgres.py with ID-preserving migration logic - Create audit_sqlite.py for pre-migration data integrity checks - Add PROJECT_PLAN.json for migration tracking - Add .secrets/ to .gitignore for credentials Audit results: 658,963 records across 29 tables, 2,390 orphaned stats (expected) Based on Major Domo migration lessons learned (33 issues resolved there)
