Hi John,
Had the same issue. Try the following steps:
1. PGHBA.CONF
This is an important file. Mine (on Linux CentOS 4) is located at
"/var/lib/pgsql/data/pghba.conf". Make sure it looks like the
following.
local all all md5
host all all 127.0.0.1 255.255.255.255 md5
2. POSTGRESQL.CONF
listen_addresses = 'localhost,*'
#port = 5432
....other settings....
3. PHP CODE
link = pg_connect("host=localhost dbname=MYDB user=MYUSER
password=MYPASS");

That is all you need. Don't specify anything else in the connection
string. Let me know how it goes.

TIP 6: explain analyze is your friend
Thanks for the sugestions but they don''t solve the problem. I do notice
that if I set listen_addresses='localhost,*' then I get the following when I
start postgres...
bash-3.00$ ps -ef | grep postgres
root 9669 8757 0 13:34 pts/5 00:00:00 su postgres
postgres 9670 9669 0 13:34 pts/5 00:00:00 bash
postgres 9673 9670 0 13:34 pts/5 00:00:00 ps -ef
postgres 9674 9670 0 13:34 pts/5 00:00:00 grep postgres
bash-3.00$ /usr/bin/pg_ctl -D /var/lib/pgsql/data start
postmaster starting
bash-3.00$ LOG: could not bind IPv4 socket: Address already in use
HINT: Is another postmaster already running on port 5432? If not, wait a
few seconds and retry.
bash-3.00$
it does start though. But if I just have localhost or * as the
listen_addresses it starts without error.
That's not my problem though this is "could not connect to server:
Permission denied" If it's denying permission I must have the permissions
set wrong but where to I start looking for them? All sub dirs in
/var/lib/pgsql are owned by postgres and seem to have the same permissions
on both systems.
Cheers
