PostgreSQL upgrade 9.3.4 -> 9.3.10

Hello,

I want to upgrade my database from version 9.3.4 to 9.3.10.

For this task, do I need to upgrade database using pg_upgrade utility?
http://www.postgresql.org/docs/9.3/static/pgupgrade.html

From the details it looks like for minor version upgrade pg_upgrade utility
is not required.
"pg_upgrade (formerly called pg_migrator) allows data stored in PostgreSQL data
files to be upgraded to a later PostgreSQL major version without the data
dump/reload typically required for major version upgrades, e.g. from 8.4.7
to the current major release of PostgreSQL. It is not required for minor
version upgrades, e.g. from 9.0.1 to 9.0.4."

Can someone please provide more details here and also what steps needs to
be done to upgrade to 9.3.10 level?

Regards...
