I am not sure exactly when this has happened but recently I am getting this warning for which I can't find any existing report or relevant post on line:

[root@km php.d]# php -v

            : PostgreSQL is an object-relational database management
            : system that supports almost all SQL constructs. PHP is an
            : HTML-embedded scripting language. If you need back-end support for
            : PostgreSQL, you should install this package in addition to the main
            : php package.

If it helps, I get the same thing without xdebug as well. I also have the pdo installed, and mysql connection through pdo works without any issue.


Expected result:
----------------
no warning in the output.

Actual result:
--------------
get a warning saying : /usr/lib64/php/modules/pgsql.so: undefined symbol: lo_truncate64 in Unknown on line 0
