# Chat Switchboard - Database Migration Runner

# ============================================

# NOTE: The Go backend auto-migrates on startup.
|

# This script is for manual/emergency use only.
|
|
# Canonical migration files: server/database/migrations/
|
|
# ============================================
|
|
# Tracks applied migrations in schema_migrations.
|
|
# In dev (DB_WIPE=true): drops all tables, re-runs
|
|
# all migrations for a clean slate every PR build.
|
|
#
|
|
# Required env vars:
|
|
# PGHOST, PGPORT, PGUSER, PGPASSWORD — app-level connection
|
|
# DB_NAME — target database
|
|
# DB_WIPE — "true" to wipe first (dev only)
