Looks like your lt_location_type column is defined as a varchar array
(i.e. VARCHAR[]), so it's expecting you to populate it with a varchar
array value (e.g. '{''foo'', ''bar''}') , as opposed to simple
varchar/text values (e.g. 'foo'). A simple alter table should resolve it
for you:

ALTER TABLE location_types ALTER COLUMN lt_location_type TYPE VARCHAR;
