pg_connect(): ... Too many open links (0)

[James Ward]

Hi all,
I've searched high and low on the web and the group for the following error:

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

I have checked phpinfo and it says max_links is unlimited, and so is
max_persistent.

It's got to be something obvious - but I can't see it.

How can I have too many links open if this is the first one!?!

I'm running postgres 7.3.4 and php 4.3.3.

I can access the database using pgAdmin - so I don't think it isn't a
permissions problem. I've got tcp/ip access enabled.

And for info the command I'm using is:

$postgres = pg_connect("host=localhost port=5432 dbname=hector
user=hector");
All help appreciated,
James

Look into the logfiles of postgres itself.
They often have more information.

Good luck,

Thanks SO much. With your help I worked it out.

I had installed the latest version of PHP with postgres support built-in.
But in the previous version I had those sorts of extensions as shared
extensions.
Because none of the config files had changed it was still loading the OLD
extensions.
Once I deleted them it worked fine.

Thanks a million,
James

I saw your post on the pg-php list and was curious. I cannot duplicate
this
at all, nor see how it is possible. The number in the "open links (0)"
message is num_links, the number of currently open links. The error
message is displayed if max_links != -1 and num_links >= max_links, where
max_links is -1 when phpinfo() reports "unlimited". So I can't see how you
can get this message if phpinfo says max_links is unlimited.

Some probably useless ideas: Check that ini_get("pgsql.max_links") really
does return -1 in that script before calling pg_connect. Don't set
max_links at all in php.ini. If you are loading pgsql.so as a shared
extension, make sure it matches the version in the PHP build. If you're
still stuck, post your platform details. Hopefully it's something really
weird.
