Re: migrating to 9.2 created blank dbs - Mailing list pgsql-admin

It has been suggested that I am misinterpreting the verbose output, which is very possible. Is the problem then with my
backupscript that works fine in 8.1 but needs a tweak to ignore whatever is triggering the attempt to create a backup
called"|"?
 

It appears that only after databases with the extra stuff at the end is when a file is created called "|"

Databases (/l command):

Any chance you’re just misinterpreting the new more verbose output of psql’s \l command?

Nowadays, it looks like this:

postgres=# \l
                                List of databases
     Name      |   Owner    | Encoding | Collate | Ctype |   Access privileges
---------------+------------+----------+---------+-------+--------------
---------------+------------+----------+---------+-------+---------
 postgres      | postgres   | UTF8     | C       | C     |
 template0     | postgres   | UTF8     | C       | C     | =c/postgres          +
               |            |          |         |       | postgres=CTc/postgres
 template1     | postgres   | UTF8     | C       | C     | =c/postgres          +
               |            |          |         |       | postgres=CTc/postgres
(4 rows)

But there are still only 3 databases being listed above.

Ifthe 8.1 server is still online it would be interesting to connect to it manually and see what you get from "select *
frompg_database”.
