Comment (by strk):

 The test in 3.3 branch is running ALL tests with
 standard_conforming_strings=off and is catching more issues:
 ​https://woodie.osgeo.org/repos/30/pipeline/1673/10

 I guess we could unleash all tests in 3.4 and master branches too, rather
 than (as we do now) restrict that test to the sole "core/regress.sql"
 file, would make sense
