Detailed Description

Union for marshalling IAID into and out of the database IAID is defined in the RFC as 4 octets, which Kea code handles as a uint32_t.

Postgresql however, offers only signed integer types of sizes 2, 4, and 8 bytes (SMALLINT, INT, and BIGINT respectively). IAID is used in several indexes so rather than use the BIGINT, we use this union to safely move the value into and out of an INT column.
