Why is PostgreSQL 8.3 not supported anymore in Nuxeo 5.5?
PostgreSQL 8.3 is not supported anymore for two reasons:
unnest
foo*
Although the first point could be worked around, the second cannot if you want to keep fulltext prefix search.
(Note also that PostgreSQL 8.3 is getting old and we can't see any compelling reason that would justify avoiding an upgrade to a more recent version of PostgreSQL — PostgreSQL 9.1 is worth it if only for performance reasons.)
