Fixed issue 2206

[Hydrocharged]

This is a fix for:

• Support for LOWER() function (ERROR: at or near "(": syntax error) #2206

I've added a skipped test to verify that the syntax error portion is fixed, however we don't yet support expression index attributes, so the test overall fails. However, the issue only covers the syntax portion which we're addressing here.

Footnotes

1. These are tests that we're marking as Successful, however they do not match the expected output in some way. This is due to small differences, such as different wording on the error messages, or the column names being incorrect while the data itself is correct. ↩
