Functions

db_error_field

Extract the column name from a PostgreSQL error. Extract a field name from a database constraint violation error, where available. On Postgres, this parses the detail field of PgDatabaseError (e.g. “Key (email)=… already exists”). On other dialects the function returns None — callers fall back to generic messages.

db_error_message

Build a human-readable message for a DB error, using the extracted field name when available.
