Обсуждение: Failed to execute pg_dump

Hi.

The problem can be caused by:

1) SELinux: may be you need set the options httpd_execmem or
httpd_can_network_connect_db. You can disable SELinux temporay with
setenfoce 0.

3) Review the option disable_functions on PHP: make sure that exec
family in not disabled.

Best regards.

Carlos M.

Apologies to Carlos for replying directly to him instead of to the list.

Both php.ini files on my system have
disable_functions =

I set the permissions to 0x777 on pg_dump but that has not made any difference.

I also set sudo to permissive, which also does not seem to have helped.

Unless I'm missing something, I think that covers all the suggestions from Carlos, Scott and Nick (who's message
doesn'tseem to be included below for some reason). Thanks for your suggestions, I'm learning things anyway :)
