Обсуждение: pgsql: Fix server crash bug in 'server' backup target.

Fix server crash bug in 'server' backup target.

When this code executed as superuser it appeared to work because no
system catalog lookups happened, but otherwise it crashes because there
is no transaction environment. Fix that.

Report and code change by me. Test case by Dagfinn Ilmari Mannsåker.
