the postgres service I get this error:

psql: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
createdb: database creation failed

I went to directory data and delete postmaster.pid and postmaster.opts but
nothing happens.
I have the same error.
PLease I need urgent help!!!

You have to start the postmaster also.

try
become root by issuing the command below and entering root
password.

$ su -

now start the postgresql service using command below

# /etc/rc.d/init.d/pgsql start

This is showing psql not connecting - you want to see what happens when you
start the backend.

Where are your logs? There should be something there. If not, start postgres
in the manner described in the installation instructions - that should show
you where the problem is.

Hi!!!
This is my log after break down::
There is a app to fix the database.

The server must be started under an unprivileged user id to prevent
a possible system security compromise.  See the documentation for
more information on how to properly start the server.

        This probably means that some data blocks are corrupted
        and you will have to use the last backup for recovery.

Edwin has said elsewhere that he is using 7.3.4 and the filesystem is
ReiserFS.  (Edwin, you should really include _all relevant_ information
when posting these things.  I don't ask just to amuse myself, you know.)

I _think_ you should make a copy of PGDATA somewhere safe; then activate
zero_damaged_pages in postgresql.conf and restart the server.  After
that, check all your data on the table with OID 17097, deactivate
zero_damaged_pages, make a backup copy of the table using pg_dump, and
try to restore whatever was lost on block 8805 of that table.  (Maybe
you could get at the data using pg_filedump or pgfsck, to be found at
http://sources.redhat.com/rhdb and http://svana.org/kleptog
respectively).

Then please if you value your data that much, do frequent backups _or_
stop using IDE disks, and maybe activate fsync if you deactivated it.

Hmm ... oops ... I'm seeing there's no zero_damaged_pages in 7.3
documentation.  So much for this solution :-(  Maybe a hacked postmaster
could do the trick?  I'm attaching a patch that seems to do the trick
(just out of CVS -- I didn't try compiling it).


PS: I'm Cc'ing pgsql-ayuda, just for the record ...

It does exist in 7.3.4.  That is what I'd recommend trying as well.
