Review comment:
After some digging around. It seems that tableNamePattern in
DatabaseMetaData.getTables() is a bit different from regular regex we are
using. In order to search for all tables, the regex should be "%" or null
instead of ".*". And we cannot use tableNamePattern to match multiple
tableNames([reference](url)). I have created another helper function to get
around this issue, and it is included in the latest commit!
