As whom a phpPgAdmin running? Probably the Apache user who may or may not have rights to see pg_dump.

Hi Everyone
I have a test server which is running Centos7, PHP 7.1.13, PostgreSQL 9.6.5 and phpPgAdmin 5.1
When I went to dump a database I received the following error:
Export error: Failed to execute pg_dump (given path in your conf/config.inc.php : /opt/rh/rh-postgresql96/root/usr/bin/pg_dump). Please, fix this path in your configuration and relog.
The path /opt/rh/rh-postgresql96/root/usr/bin/pg_dump is valid.
I have checked the /user/share/phpPgAdmin/conf/config.inc.php which appears to be the configuration file mentioned in the error message and I can’t see any obvious issues.
I searched this problem in the mailing list but could not find any recent results. I did find an older result which said to correct the path in the config file, but that looks right to me.
