pg_connect(): Cannot create new link

I have the same problem posted by James Ward (Date: Mon, 15 Sep 2003)

I migrated from (postgresql-7.3.2-3 and php-4.2.2-17) to
(postgresql-7.3.4-2 and php-4.3.3-6).

When I connect to the Database via php, I get the following message:

Warning: pg_connect(): Cannot create new link. Too many open links (0).

I didn't change any configuration file: everything used to work.
It's the first connection to the database
(max connections should be 32 by default).

Is it a bug ? Any solution?
Is there a chance to bypass it?

Thanks a lot.

What does

ps ax|grep postgres|wc -l

say? If it says 34 or so, then yes, you have that many connections. You
may have a problem with your apache processes hanging / dying oddly and
keeping the postgresql connections open. restart postgresql with

pg_ctl -m fast stop
pg_ctl start

and see if you can connect.

Did you check for the same situation which was causing him the problem?

Try replacing your php.ini file with a default distribution file.

Re: pg_connect(): Cannot create new link

In my /etc/php.ini file I had this line:
extension=pgsql.so
(now removed).

; Note: For Red Hat Linux, packaged extension modules are now loaded via
; the ini files in the directory /etc/php.d.

# ls -l /etc/php.d
-rw-r--r-- 1 root root 51 10 nov 16:40 pgsql.ini

# cat /etc/php.d/pgsql.ini
; Enable pgsql extension module
extension=pgsql.so

Thank you for help!
Now it's ok!!

Mauro
