PR Summary

Medium Risk
Medium risk because it changes a schema migration to drop a uniqueness constraint earlier, which affects production data constraints and could allow unexpected duplicates if the later composite indexes don’t apply as intended. The migrate script change is low risk but will increase log verbosity and may expose query text/parameters in logs.

Overview
Updates migration 0194_careless_pete_wisdom.sql to drop the legacy global unique index on permission_group_member.user_id earlier (before the clone insert), preventing uniqueness violations during permission-group/member cloning, and removes the later redundant drop step.

Enhances packages/db/scripts/migrate.ts error handling by printing Postgres driver diagnostic fields (e.g., code, constraint/table/column, hint) plus failing query/parameters, nested causes, and stack traces to make failed migrations easier to debug.

Greptile Summary

This PR makes two improvements to the migration tooling: it moves the DROP INDEX permission_group_member_user_id_unique earlier in migration 0194 (before the workspace-clone INSERT) to prevent a constraint violation during cloning, and it replaces the bare error.message log in migrate.ts with a comprehensive printMigrationError helper that surfaces all PG-specific error fields (code, detail, hint, constraint, table, etc.) as well as the failing query and cause chain.

Confidence Score: 5/5

Safe to merge; the SQL fix is correct and the only finding is a P2 naming mismatch in the logging helper

Both changes are low-risk: the SQL migration fix is a correctness improvement to an existing migration, and the migrate.ts change only affects error logging output. The one identified issue (snake_case vs camelCase field names) means a few diagnostic fields would silently not print, but does not affect migration correctness or CI.

packages/db/scripts/migrate.ts — camelCase field names should be verified against the postgres.js driver
