added a test case for tables in CamelCase

[yktv4]

I decided to remove all unnecessary quote_ident usages in the procedure. Since the fix is not backwards compatible, according to https://semver.org, I needed to also bump the first non-zero character in the version, hence the new version is 0.3.0.

See my motivation in #16 .

Hi,
thanks for taking the time to provide this PR.

I like your clean solution and think that indeed asking the developer to provided a properly quoted and escaped table name is the best solution.

I've created a new PR incorporating your changes here: #21 because I:

• needed to solve some conflicts
• wanted to change the name of the tests to upper_case, as this is not specific to camelCase
