Re: When I try to connect to a database, I get the following error : psql teleflowdb8

When I try to connect to a database, I get the following error :

psql teleflowdb8

psql: FATAL: database is not accepting commands to avoid wraparound data
loss in database "teleflowdb8"
HINT: Stop the postmaster and use a standalone backend to vacuum database
"teleflowdb8".

Then I try to go to standalone mode:

$./postgresql-8.2 stop
$su postgres
$cd /usr/lib/postgresql/8.2/bin

$./postgres --single -D /var/lib/postgresql/8.2/main/ teleflowdb8

I got the following error :
--single cannot access the server configuration file
"/var/lib/postgresql/8.2/main/postgresql.conf": No such file or directory

When to check the postgresql.conf file is located at
/etc/postgresql/8.2/main

$ls

environment
log
pgdata
pg_hba.conf
pg_ident.conf
postgresql.conf
start.conf

So I did :

$./postgres --single -D /etc/postgresql/8.2/main teleflowdb8

But error as follows.
2012-02-24 19:04:28 SGT FATAL: "/etc/postgresql/8.2/main" is not a valid
data directory
2012-02-24 19:04:28 SGT DETAIL: File "/etc/postgresql/8.2/main/PG_VERSION"
is missing.

I do not have the /var/lib/pgsql/data directory.

Can anyone help on this issue. TQ
