Обсуждение: database "postgres" does not exist
Hello everybody
We have a very strange problem here: we have been using postgresql for
several years now, it runs fine without any problem.
BUT today, we saw something I do not understand:
when I try to use psql like this:
sudo -u postgres psql
I get the message:
psql: FATAL: database "postgres" does not exist
About 1-2 months ago, this was OK
I know this message is current on a new installation when the system is
NOT initialized.
But what puzzles me here is that the database postgres DID exist... but
it seems to have suddenly disappeared !!!!
A part from this, everything works fine, for example the command:
sudo -u postgres psql -d template1
works, and the postgres applications run quite smoothly
So, here is my question: how such a thing could have happen ? We cannot
remeber any stupid thing we could have done (but may be we did... And
what do I have to do to recreate the postgres database... in fact, is it
even necessary doing so ?
The OS is a 64bits Debian (distribution testing, dist-upgraded today but
this did not correct the problem)
The postgres version is 8.1.4
Thanks in advance,

If you issue "\l" from within the posgresql command prompt does it list postgres as a database? If it does not show up, my guess is that is was dropped. Regards, Richard Broersma Jr.
Richard,
Are you sure that you weren't typing an additional argument, such as:
sudo -u postgres psql db_name
Reason I ask is because, by default running the command psql assumes
some things if you don't call them out explicitly such as:
psql assumes:
-h 127.0.0.1
-p 5432 (or whichever was compiled in)
user_name (database name, named that of the user)
user_name (user name, named that of the user)
so when you type:
sudo -u postgres psql, I think it's interpreted as:
sudo -u postgres -h 127.0.0.1 -p 5432 postgres postgres
sudo -u postgres psql -d template1 (implies a user of postgres) and that's why it works.
