    M ut.h

  Log Message:
  -----------
  cachedb_mongodb: Return DB_STRING strings, not DB_STR

Several modules relying on SQL data do not fully handle the DB_STR data
type, e.g. drouting.  So when db_cachedb is used on top of
cachedb_mongodb, these modules may report errors such as:

ERROR:drouting:dr_load_routing_info: column gwid has a bad type [4],
	accepting only [3]

Many thanks to Sasmita Panda for the report and helping with testing!
