The pytest fixtures were improved to allow running with a
core.sqlite_dos
storage for the test profile, making PostgreSQL completely optional. However, the current fixture still imports thepgtest
package at module level making it a requirement, despite it only being relevant when running the tests with acore.psql_dos
storage plugin.Here the import is moved inside the
PostgresCluster._create
method which is only called when the test suite actually uses a PSQL based storage plugin.
