existence of "integrity checking" tools means the DBMS is done with
high incompetence.
It depends on what you mean by integrity. If you mean "Does the database have the data I THINK it's supposed to have".. that's all up to you when you design your schema (FK's, Unique, etc..) and your app developers:
'Where thou wouldst type foo, someone else would surely type supercalafragilisticexpialadocious'
(paraphrased)
If you're asking "Does the database have the ability to verify that whatever is in a block is what was put into that block", then Oracle has block check-summing (I'm not sure if this got into PG 8.4 or not...) . I'm not sure if there is a checksum on the datafiles themselves, but I would guess in the affirmative when talking Oracle.

This is talking about "Does the database have what I think it should?" and can't really be done unless you had some auditing system setup to compare it to.
