postgresql - How to create production database sample for testing? -

-

is there tool (for posgresql, ideally), can make small, consistent sample of big database?

the need testing database, don't want copy production one. first, because big , second, nature of testing implies testing database recreated several times in process.

obviously, can not take random rows tables, because violate hell out of foreign keys , not. so, wonder there tool available can that?

what generating mock data tool databene benerator, as want, , store them reuse.
