Hi,

After installing Davical and Postgresql (9.1) on Ubuntu 12.04, I tried to run the create-database script. First, the script fails because it cannot connect to the database (at this point it has already created the database and the two users). I did have the correct entries in pg_hba.conf and had restarted postgresql.

I upgraded a server with a Rails application to Ubuntu 12.04 from 10.04 and cannot connect to Postgresql database now...

Here is the error message from Rails app:

could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"

Also the pg_ctl start is not recognized as a command.

Snort update, broken. 2 years 19 weeks ago

Hmm.. i didn't know which board to put this on, but anyway.

i am having trouble updating snort on ubuntu lucid.

I have 2 cluster databases, running on the same host, Ubuntu. My fist database port is set to default but my second database port is set to 5433 in the postgresql.conf file. While everything is ok with local connections, I cannot connect using any of my tools to the second database with port 5433, including pgAdmin. Please help.

Help! I am trying to connect to a Postgres database and can't get the server to connect. When I execute this php script:

$conn = pg_connect("dbname=wikimap user=postgres password=postgis host=localhost port=54321"; if (!$conn) { echo "Not connected : " .

The following command runs fine, that is, doesn't ask for a password, prints no warnings or errors, and simply provides a DB prompt:

$ psql -U dbuser dbname psql (8.4.10) Type "help" for help.

dbname=#

When trying to generate an ERD out of this DB with SchemaSpy (running as the same host user), it doesn't work:

$ java -jar ~/schemaSpy.jar -dp /usr/share/java/postgresql.jar -t pgsql \ -host l
