# offsets within the tuple. We choose a structure without padding on all
# supported architectures:
#
-# a BIGINT
+# a BIGINT
# b TEXT
# c TEXT
#
# xx xx xx xx xx xx xx xx 'b': xxxxxxxx offset = 32 CCCCCCCC
# xx xx xx xx xx xx xx xx 'c': xxxxxxxx offset = 40 CCllLL
# xx xx xx xx xx xx xx xx : xxxxxxxx ...continued
-# xx xx : xx ...continued
+# xx xx : xx ...continued
#
# We could choose to read and write columns 'b' and 'c' in other ways, but
# it is convenient enough to do it this way. We define packing code
