Excerpts from Azlin Rahim's message of mar may 25 18:23:13 -0400 2010:
In our database list, there is one 'mysterious' database with a blank name.
We don't know how it got there.
Maybe somebody SQL-injected you and created it.
Below is the output of pg_database. Does anyone have any idea why this is
happening? Any way to remove the 'mysterious' database safely.
I'd investigate a bit more what's inside, before deleting it. Maybe the
name has only whitespace or control chars. You can use double quotes to
refer to such names. For example, this is a name a space and a
backspace:
=# create database ^?;
CREATE DATABASE
You can see the ASCII chars that make up the name with something like this:
=# select datname, ascii(substring(datname, generate_series(1,
length(datname)), 1)) from pg_database;
\x7F |32
\x7F | 127
Now if somebody messed with an Unicode control char, I don't know what
to tell you.
