I'm reading the documentation on:
U++ SQL
Basic Use and Description

And it says :
Note: In U++, we tend to use uppercase for all database/table/column names. Also, some databases, like PostgreSQL, have case-sensitive database, table, and column names. Writing queries can be a pain when you have names that have a mix of upper and lower-case letters. By default, unless you use quotes, all names in the macros will result in lower-case names for all tables/columns created.

But in reality in all examples the names are not converted to lower case, they remain upper case.

Which one is wrong the documentation or the code ?

Thanks in advance for your time, attentin and great work !

Here is an attempt to make the names lowercase:

Documentation is wrong here... Even in the point of PGSQL being case sensitive (it is not).
