Thank for you for the explanation. Now that I understand the logic
behind the scenes, the process looks fine to me. 

However, could you please explain what is happening below and how I
should fix this:

[dd]
Fetching postgresql92-client-9.2.10_1.txz: 100%  991 MiB 146.2kB/s    00:36 ETA
Fetching php5-pdo_pgsql-5.4.39.txz: 100%   17 KiB  17.6kB/s    00:01
Checking integrity... done (2 conflicting)
pkg: Cannot solve problem using SAT solver:
dependency rule: package php5-extensions(r) depends on: php5-ldap(r)php5-ldap(l)
dependency rule: package php5-extensions(l) depends on: php5-ldap(r)php5-ldap(l)
upgrade rule: upgrade local php5-ldap-5.4.39 to remote php5-ldap-5.4.39
cannot install package php5-ldap, remove it from request? [Y/n]: pkg: cannot find php5-ldap in the request
pkg: cannot solve job using SAT solver
Checking integrity... done (0 conflicting)
Conflicts with the existing packages have been found.
One more solver iteration is needed to resolve them.
