[Geocoding] Turning on fsync and full_page_writes after installation

[Simon Nuttall]

After 10 days on a 1.2TB / 32GB Quad Processor a full planet import
has completed and is continually running minutely updates. Great!

The installation instructions say:

66
For the initial import, you should also set:

fsync = off
full_page_writes = off

Don't forget to switch them on again afterwards or you risk database corruption.
99


So my question is how to turn these back on. It seems they need to be
set in the postgresql.conf file.

Presumably that means restarting postgresql - so how do I do that
without corrupting the data?

Also I'll have to restart the minutely updates afterwards, but how do I do that?

It seems that the nominatim could be made into a service that can be
stopped and resumed.
