You should change the comment to a block comment in the then clause rather than as a tail comment.
Tail comments need to be very short since there is usually not much room on the end of the line.</pre>

module reload cdr_pgsql.so
will cause the columns list to get doubled up (because they aren't cleared) which will make insertions fail since the insert statement will have all of its elements repeated.
This patch does two things. Well, three. First it unregisters cdr_pgsql from cdr.c so that cdr logs won't try to use this cdr storage method while the reload process is happening (re-registration occurs at the end of the reload). Second, it clears the columns list during reload so that it doesn't end up doubling up the entires. As an irrelevant third, it updates the copyright status in the documentation to 2012 from 2006 or so.</pre>
