To make this work, try:
select "firstName", "lastName", "Email" from people ;

Right, it's the SQL quoting rules. A bare name is taken to mean an
identifier (table name or field name), which is then downcased before
lookup. Quoting with double quotes (") indicates an identifier that is
used directly, without downcasing (or validation against reserved words:
you can make very odd tablenames that way). All string values need to be
quoted with single quotes (')
idas=> select test;
ERROR: attribute 'test' not found
idas=> select 'test';
?column?
--------
test
(1 row)
idas=>
I don't know perl, but you need to get the single quotes around all the
values.
Hope this helps,

P.S. This question probably belongs on the interfaces list, not admin.
