What if the page file exceeds the shared_buffers, but you can't increase the
shared buffers to a larger amount? For example, page file is set to be
between 500MB and 10GB, but you can't set the shared_buffers to more than
1200MB. If set to 1300MB or higher then service will not start.

Please see "GEOS union() error" thread for more details.
