conection problem after upgrade to php5 and postgres 8.0.3

["John Coulthard" <bahhab@xxxxxxxxxxx>]

Hi,

I've had to rebuild our web server and now my php scripts will not connect 
to postgres can anyone tell me why?

Thanks for any help, details below.

I was using Redhat9, postgres 7.3.4, php 4.2.2 and apache2
now using  Fedora core 4, postgres 8.0.3, php 5.0.4 and apache2

I know php is configured for psql 
http://zeldia.cap.ed.ac.uk/Lumbribase/php_info.php

In postgrsql.conf I tried changing listen_addresses = 'localhost' to 
listen_addresses = '*' but that didn't work.

I think the pg_hba.conf is OK..
# "local" is for Unix domain socket connections only
local   all         all                                 ident sameuser
# IPv4 local connections:
host    all         all         ***.*.*.*/**          ident sameuser
# IPv6 local connections:
host    all         all         ::*/***               ident sameuser

The error in /var/log/http/error_log is...
[client ***.***.***.***] PHP Warning:  pg_connect() [<a 
href='function.pg-connect'>function.pg-connect</a>]: Unable to connect to 
PostgreSQL server: FATAL:  Ident authentication failed for user 
&quot;webuser&quot; in /var/www/html/Lumbribase/pg_name.php on line 17, 
referer: http://zeldia.cap.ed.ac.uk/Lumbribase/search_id.php

and a typical php connection script is...
$PG_HOST="localhost";
$PG_PORT=5432;
$PG_DATABASE="lumbribase";
$PG_USER="webuser";
$PG_PASS="";
$PI=pi();

$dbconn=pg_connect( "dbname=$PG_DATABASE host=$PG_HOST port=$PG_PORT 
user=$PG_USER password=$PG_PASS" );
if ( ! $dbconn ) {
   echo "Error connecting to the database !<br> " ;
   printf("%s", pg_errormessage( $dbconn ) );
   exit();
}
