Sorry, meant GDBM (disk based hash/lookup table).
With Postgres if your tables fit into RAM then they are in-memory as
long as they're actively being used.
Hashtables and GDBM, as far as I know, are only useful for key->value
lookups. However, for this they are *fast*. If you can figure out a way
to make them work I'll bet things speed up.
