As far as I can see by review, this PR will not work if either the schema name or the table name or both contain a dot, which is quite valid when the name which has a dot is name quoted. E.g. "my.schema"."my.table" is a valid schema, table combination.

Another question is why does this PR add that functionality only to the getTableColumns method and not to any other method which takes a table name as argument.

So in my opinion this PR should not be merged as it is. But other opinions are welcome.

@softarius It seems you had rebased your branch locally to 3.x-dev and pushed the changes, but the PR on GitHub was still against the 2.0-dev branch. That's why it has shown so many unrelated changes.

I have fixed that now by rebasing to 3.x-dev on GitHub. Now it look ok again.

As far as I can see you have also resolved my previous comment. I will check and review again when I have more time.
