## Tests
64+
65+
$ make check
66+
67+
This command runs:
68+
- regression tests;
69+
- isolation tests;
70+
- tap tests.
71+
72+
One of the tap tests downloads a 1GB archive and then unpacks it
73+
into a file weighing almost 3GB. It is disabled by default.
74+
75+
To run this test, you need to set an environment variable:
76+
77+
$ export PG_TEST_EXTRA=big_values
78+
79+
The way to turn it off again:
80+
81+
$ export -n PG_TEST_EXTRA
82+
