# We need to dispose of any engines created during tests or else the
# engine's QueuePool will leak connections even once this suite has
# finished running. Then as other test suites start to run, the number
# of connections will eventually creep up to the maximum number that
# postgres allows. For reference, see the SQLAlchemy docs here:
# https://docs.sqlalchemy.org/en/13/core/connections.html#engine-disposal
#
# This pattern should be repeated in any test class that creates a
# PostgresContentsManager or a PostgresCheckpoints object (note that
# even though the checkpoints manager lives on the contents manager it
# still creates its own engine). An alternative solution to calling
# dispose here would be to have these classes create engines with a
# NullPool when testing, but that 1) adds more latency, and 2) adds
# test-specific behavior to the classes themselves.
