issue2550549 Postgres error on message templating Exception gets thrown and not captured if nodeid is too large on postgres. Added a check in rdbms_common layer that max nodeid is < 2^31 -1. This is also the limit for INTEGER on MySql. SqlLite can support up to 2^63-1, but I chose the smallest common denominator. Large nodeid should now returns no such id rather than a stack trace.
