I believe Adrian wanted to know whether you attempted a
schema or complete dump *after* the fact, like what he
suggested a mail ago or so.
In case the FS corruption "only" affects raw files related to
user data (as opposed to also affecting data in pg_* tables)
a schema-only dump does have a slight chance of success.
That chance might potentially be increased by judicious use
of zero_damaged_pages and related low-level techniques the
prerequisite conditions of which people seem to have been
trying to inquire about upthread.

"possible" depends no the exact circumstances, the details of
which people have been trying to tease out.
