[Pkg-postgresql-public] Bug#742493: pgmemcache segfaults with libmemcached11

[Christoph Berg]

Hi,

when rebuilt with libmemcached11, pgmemcache in Debian started to
segfault. It worked with libmemcached10 before.

I'm not sure whose fault this is - pgmemcache or libmemcached, or
possibly both. Hannu, Michael, could you have a look at this?

(Unforatunately I couldn't find an email for libmemcached, just the
launchpad tracker.)

Version: 2.1.2-1+b1
Severity: grave

The binnum to update the dependency from libmemcached10 to
libmemcached11 seems to have broken the PostgreSQL module:

Also in my chroot:

test test                     ... FAILED (test process exited with exit code 2)
test stop_memcached           ... ok
