$ apt-cache show libicu52|grep Installed-Size
Installed-Size: 27283

That's 27MB or less than 2 WAL files. Or about 4 times the template
database, or which 3 are created during install and the first user
database will be a fourth.

The installed size of Postgres is 11MB not including any of the
libraries it already depends on.

Yes, it's not a small library but lets not get carried away.

And if it's optional then low memory systems can configure it out.

As for configuration, ICU doesn't require configuration just like glibc
doesn't require configuration.
