Today I ran the "usual" things I did hundreds of times, and I
had a strange "bug". I'm not sure whether it's a bug in
liquibase or in Java 8, but this is what happened:
`liquibase update` against a RedShift DB displayed the same error
we had in http://forum.liquibase.org/topic/redshift-support ,
because it doesn't add the escaping double-quotes around the reserved
keyword of RedShift: TAG
Took us some time, but finally we found out that the fix was to run
liquibase with Java 7 instead of 8.
