It will be the result of using different tools to create the two database
versions. Double-quoted identifiers are optional (except when "illegal"
characters are used in the identifier) but some database tools enforce
double quotes by default. When DQ identifiers are used, all references to
them in SQL must include the DQ's.

Since DQ identifiers are also case-sensitive, the two versions of the
database are not equivalent.

For example,

create table "aTable" ("id" integer, "data" varchar(20))

is different from

create table aTable(id integer, data varchar(20))
