pkg: WARNING: locally installed postgresql93-client-9.3.3 conflicts

[Sergei G]

I run command
sudo pkg install adminer

and got a WARNING:

pkg: WARNING: locally installed postgresql93-client-9.3.3 conflicts on
/usr/local/bin/createdb with:
        - postgresql92-client-9.2.8_1

Should I ignore it? What impact does it have?
