A comment on Poll: What database do you use in production?.
SQLite (yes, it is useful in production)
kdb+ (it's kind of specialized, but so are vertica and greenplum)
HyperTable (if hbase is there ...)
Tokyo/Kyoto Cabinet (if redis is there ...)
On second thought, this might be already too spread out, too many options already for a meaningful survey
