Don't print database's tablespace in pg_dump -C --no-tablespaces output.

tglsfdc · tglsfdc · commit 142a110b312f · 2016-09-08T10:48:03.000-04:00
If the database has a non-default tablespace, we emitted a TABLESPACE
clause in the CREATE DATABASE command emitted by -C, even if
--no-tablespaces was also specified.  This seems wrong, and it's
inconsistent with what pg_dumpall does, so change it.  Per bug #14315
from Danylo Hlynskyi.

Back-patch to 9.5.  The bug is much older, but it'd be a more invasive
change before 9.5 because dumpDatabase() hasn't got an easy way to get
to the outputNoTablespaces flag.  Doesn't seem worth the work given
the lack of previous complaints.
