I'm a bit skeptical about changing anything here. There are quite
a large number of GUCs that can affect the regression results, and
it wouldn't be sane to try to force them all to fixed values. For
one thing, that'd be a PITA to maintain, and for another, it's not
infrequently useful to run the tests with nonstandard settings to
see what happens.
Is there a good reason for being concerned about work_mem in particular
and this test script in particular?
