Re: Read db files directly

Thanks Scott.

Well, PostgreSQL runs just fine.
As I said, I can create new db, new tables, etc.
everything works just fine for new stuff.

when I say psql shows nothing,
I really mean "nothing".
No error messages.

Of course if I create a new db, psql -l shows my
new db.

psql -l
       List of databases
  Name  |  Owner   | Encoding
--------+----------+-----------
 testdb | postgres | SQL_ASCII
(1 row)


What I am curious about is, what are
in those 50 GB worth of files.
"strings" shows me there are some data that
I might be interested in saving before I erase
this pg instance.
