Incorrect values being printed by assert_select.

Digestor should just rely on the finder to know about the format and the variant -- trying to pass it back in makes a mess of things (oh, and doesnt work)

Postgres schema: Constrain sequence search classid

assert_raise + assert_equal on the returned exception message work
just fine, there is no need for extra work, specially like this overly
complicated helper.

The pk_an_sequence_for query previously joined against pg_class's oid
for rows in pg_depend, but pg_depend's objid may point to other system
tables, such as pg_attrdef.  If a row in one of those other tables
coincidentally has the same oid as an (unrelated) sequence, that
sequence name may be returned instead of the real one.

This ensures that only the pg_depend entries pointing to pg_class are
considered.

Just pass in the expected database as argument rather than "caching"
it in a hash and using the hash in the helper methods.

Also fix indent of test block.

ActiveRecord#touch should accept multiple attributes

Cleaning up and adding tests for Session

Adding tests for Session `destroy`, `update` and `delete` methods. No changes for code under test.

Refactor to a reusable method.

No need to check that each line contains an extra space, just matching
the space in the regexp is enough to ensure that.
