Defined in:

Overview

Loads a SQL dump by shelling out to psql. The psql subprocess uses its own Postgres connection, so the loaded data commits immediately and does NOT participate in the caller's transaction (a transaction is per-connection; a child process can never join it).

This is the default strategy of load_real_test_data. Prefer the Native strategy (load_real_test_data_native) unless the dump requires psql itself — e.g. psql meta-commands (\set, \connect) or dumps too large to read into memory.

def call(dump_path)
  # Load the SQL dump quietly. Invoked without a shell (argv array +
  # :in redirect), so paths and connection values need no escaping.
  # Note: no transaction or session_replication_role handling here —
  # psql runs on its own Postgres session, so nothing set on the
  # ActiveRecord connection can affect the load.
