It looks like the table is being defined with the column quoted, like
this:

create table one ("Name" text, moredefshere...)

but accessed without quotes, like above. Whether a database folds to
upper or lower case, the columns need to be accessed consistenly, either
all quoted or never quoted. An application that mixes quoting and not
quoting identifiers is going to have problems.
