Hi,
By that I mean the following:
$ rpm -q --scripts postgresql94 | egrep 'psql|pg_config'
/usr/sbin/update-alternatives --install /usr/bin/psql pgsql-psql
/usr/pgsql-9.4/bin/psql 940
...
As a result, psql is available right away after installing the
package. But not so with pg_config. Is it by design or by accident?

Yuri
