Finally! True serializability! Never let anyone (including the docs for older postgres versions) tell you that predicate locking is too hard to implement.
Kevin Grittner will be talking on Serialization this Friday,
September 16th 11:30 a.m. – 12:30 p.m. His talk will be recorded... so those who aren't in Chicago can see/hear it later next week.
