#144450 by wall_unit: CREATE TABLE script for PostgreSQL doesn't work.
#216220 by guardian: Install broken on installs with prefixed tables

Cleaned up some of the code, added some comments, tried to improve coding standards.

The problem was in _lineage_get_parent_lineage, which seems to never have
worked. All terms were given a depth of 0, and only fixed when
lineage_update_all was called. I've also added a call to lineage_update_all in
the install file so that previously broken installs will be fixed.
