Removed unused DB-adapters, test cases, 60+% cover

We are not using OracleDB, PostgresDB, and VerticaDB, so there is no
need to keep the "dead code" -- we can always add it back as needed.
Added test cases so that all the files are at least minimally covered.
Overall coverage on my local tox shows 66% coverage (I manually ensured
all files are included in the coverage report).
