PostgreSQL & PHP connection problem

Question

Folowing this question by CountZero, apparently i'm facing same problem here. When my site trying to open connection with the database, SOMETIME (Not Always) i get following error:

Warning: pg_connect() [function.pg-connect]: Unable to connect to PostgreSQL server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. in E:\htdocs\trial_pg\client_1a.php on line 3

Here is my client1a.php script:

<?php
  $connString = 'dbname=movies user=xxxxxx password=xxxxxx';
  $connHandler = pg_connect($connString);
  echo 'Connected to '.pg_dbname($connHandler);
?>

This happens often, especially when I refresh the page (F5) repeatedly to test the connection. I'm new with postgresql, and this is the developing environment of my site:

OS: Windows 7 Professional

Web Server: Apache/2.2.14 (Win32) DAV/2 mod_ssl/2.2.14 OpenSSL/0.9.8l mod_autoindex_color mod_apreq2-20090110/2.7.1 mod_perl/2.0.4 Perl/v5.10.1

PHP: 5.3.1

PostgreSQL: 8.4.3

Are there any configuration i miss? Any hints?

Thanks!

The script name it is looking for has an '_' (underscore). client_1a.php — user201788

Could it be that php doesn't immediately close the connection on script end? I see no explicit pg_close() in your code. Look at the postgres logs for any possible details of this. — Fanis Hatzidakis

PHP should run pg_close automatically at script end. How many times are you trying to open the connection (per script run)? Once? Twice? More? Look for max_connections here postgresql.org/docs/8.4/static/runtime-config-connection.html then check your config, if you're at default of 100 that should be plenty, and sounds like it's something with the server itself. If you're opening 20+ connections on each script run (instead of reusing them) Then that could be the problem. — Viper_Sb

@AJ: Hmm, it should be client_1a.php. Thanks for the correction :) — GuyFreakz

Sometimes this kind of problems are caused by over-enthusiastic antivirus software, if it monitors TCP connections. Do you have any antivirus running there?

I don't think so. I've been using Eset Smart Security for over 2 yrs and it's working fine even for Oracle. I think the problems is the postgresql itself ;)
