php5-pgsql depends on postgresql92, but I have postgresql93

I don't know how to resolve the problem of php5-pgsql requiring
postgresql92-client: 9.2.8_1, but my system already uses
postgresql93-client-9.3.4.

Below is output of commands to demonstrate the issue.

$ sudo pkg install php5-pgsql

Password:
Updating repository catalogue
The following 2 packages will be installed:

Installing postgresql92-client: 9.2.8_1
Installing php5-pgsql: 5.4.29

The installation will require 9 MB more space

0 B to be downloaded

Proceed with installing packages [y/N]: N

$ pkg info | grep postgresql
postgresql93-client-9.3.4 PostgreSQL database (client)
postgresql93-server-9.3.4 The most advanced open-source database
