----------------------------------

Thanks for your contribution!  The patch will eventually be committed into the trunk, and
thus the convention is to base the patch on the version of code in the trunk.

> I changed DirectPostgresManager.java to special-case rewrite COPY.... command for boolean
fields so that hive sees "true"/"false". The only shortcoming with my patch is that because
PG jdbc driver can not tell bit data types from booleans, direct import will break with SQL
cast errors if someone has real bit fields. Not sure how often people use those, but it will
break direct import for that one person who does. If you have an idea on how I can make this
better, let me know. Diffs are attached
