Re: Authentication Question

There is no hostname specified in the PHP code when it connects to PostgreSQL, so it's using a socket connections
thencorrect?  Also, I did SIGHUP the PostgreSQL server after the configuration changes.  Here's what the PHP config
filelooks like that's used to connect to PostgreSQL 

$db = array(
    "type"    =>    "pgsql",
    "host"    =>    "",
    "port"    =>    "",
    "name"    =>    "issue-tracker",
    "user"    =>    "webuser",
    "pass"    =>    "password"
);


    I wonder if  it's trying to authenticate because there's a username and password specified in the pg_connect()
function. However, when I remove the username and password I get the following error... 

Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL: IDENT authentication failed for user
"dbname=issue-tracker". in /var/www/html/issue-tracker/includes/classes/dbi.class.php on line 98 " 

Thoughts?

This is correct if you specify a host name:

pg_connect("host=local dbname=db")  <- TCP/IP
pg_connect("dbname=db") <- local unix sockets (i.e. no host=)
