jochen e0e97a96c4 Report as revoked only what the read-back shows gone, and take back what the reader passed on (review of hq issue 337)
mesh/merge-gate pass: builds postgres, sent nowhere; no bus step; 2 wait(s) for a person; every machine composes with the change as it did without (4 of 4 …
mesh/repo-check pass: its merge-check.sh passed
mesh/delivery delivered
A reader given a privilege WITH GRANT OPTION that passed it on made the
plain revoke fail with dependent privileges exist; the pass still listed the
table as revoked and logged it every minute. The pass now retries such a
change with CASCADE, which reaches only grants that came from the reader,
reads the grants back, reports as revoked only what is gone, and says what
is still held and why when anything is.

jochen 8bf50f7555 Revoke the reader's grants as their own grantors and read them back, alter its role only on drift, and report definer functions and views (review of hq issue 337)

mesh/delivery superseded: a newer head of the same pull request
A superuser's REVOKE acts as the table owner, so a grant to the reader made
by a role holding GRANT OPTION survived it while the report said revoked.
Each grant is now revoked under SET ROLE to its grantor, the grants are read
back, and anything still held is reported as a failure. The role was
altered every minute with its password in the statement, which a server
logging DDL would record and which could collide with a first query; it is
now altered only when an attribute, a setting or the password has drifted,
one ensure at a time. SECURITY DEFINER functions and views the reader may
use reach data without a grant on it, so every pass lists them. The README
says the name filter is a backstop and that the read-only session default
can be turned off by a statement.

jochen 4f44bf1eb5 Give the store's reader only the columns a module declares readable, never a secret, so a query cannot read the controller's signing key (hq issue 337)

mesh_store_reader held pg_read_all_data, so every caller of mesh-store.query
and postgres_query could read every column the store holds: the signing key
nodes trust, sealed secrets, password hashes. The reader now holds no role;
each minute, on every database, its memberships are revoked and its grants
brought to what the consumer's contribution lists under readable, minus any
column or table whose name says it holds a secret. Before a statement runs,
the reader's own session is asked which secret columns it can read and the
statement is refused if any; a statement naming a known secret table is
refused before it is sent.
