Обсуждение: Forgotten the master password of db

Hi,

unfortunately I have forgotten the mpassword of the master user of a db.
Is there a way to retrieve it using the user who owns the db template1?

Thx

Thiemo

No, but you can temporarily set the authorization policy (pg_hba.conf)
to something other than password; log in as the superuser without any
password; assign yourself a new password.

I shall try so.

Thanks

No, you can't retrieve it.  You can change it, though, as the postgres user:
ALTER USER the_user WITH PASSWORD 'new_password';

Hi guys,

I got a bit of an interesting problem I'm hoping someone can help me solve.

I've got a table that's got over 12000 entries in it     and user's can run
searches on it via the
web.  Now, I only ever want to return a maximum of 500 results (for speed
purposes) for any search.

Now, I've got that right by using the LIMIT command, but I also want to be
able to tell the user
how many records matched their search criteria.  So I want to say something
like

"Your search matched 1234 items.  These are the first 500" or some such
thing.

Is there any way, IN ONE QUERY, to do this.  So I want to basically return
the first 500 results
and a count of the total result set in one go.  Is this possible?

If not, what would be the quickest way to do this?  The reason I need one
query is because I use
dynamic SQL, which complicates stuff a bit more

Thanks

Rob

It is certainly possible to do this, if not efficient.

You can always just union two queries together using an extra column that
is null for the real records and returns the full count in a special
record. Order by can be used to make this record first or last.
