... original commit at https://github.com/rails/rails/commit/b489dbf9e361c733
update rails 4.2 (master) - hopefully it test will get a bit greener
probably best to not realy on OID from AR itself (until it's made shareable by core)

... avoid possible :
ArgumentError: A copy of ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::OID has been removed from the module tree but is still active!
align Postgre's OID module names-space with the new one proposed for AR 4.2
+ use a mutex instead of a java.lang.Object
align Postgre's ArrayParser module names-space with the new one proposed for AR 4.2
