 /*
  * If the unaccent extension is installed, modify the cspace_english text search configuration to
  * be accent-insensitive.
+ *
+ * Also replace the nx_to_tsvector function generated by nuxeo. This is identical to nuxeo's
+ * implementation, except that it searches all namespaces for the cspace_english text search
+ * configuration, instead of using "public.cspace_english", as configured in
+ * proto-repo-config.xml. This is to work around Amazon RDS renaming the public namespace to
+ * something random during database restores.
