+In production, the column `mode` of the table gallery_usergallery contains both
+lower case 'w' and upper case 'W':
+
+SELECT mode, COUNT(*) AS nb FROM gallery_usergallery GROUP BY BINARY mode;
++------+-------+
+| mode | nb    |
++------+-------+
+| R    |    10 |
+| W    | 22693 |
+| w    |   603 |
++------+-------+
+
+while only the upper case 'W' is actually recognized (see value of
+zds.gallery.models.GALLERY_WRITE). This comes probably from the the permission
+modification of galleries when a member unregisters itself: the lower case 'w'
+was hard-coded.
+
+
+This migration changes 'w' to 'W'.
