Hi Charles,

Start by creating a JIRA and then you can do more or less what was done for
EXASOL dialect [1].
Tests for dialects are usually added in RelToSqlConverterTest as you can
see also in [1].
If the new dialect is very similar to an existing one then maybe there is
no reason to create a new one.

Best,
Stamatis
