Subject: Do not define type for a property graph
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=891a57c73945c0dcf942810f604bbd90d724b9ed;p=thirdparty%2Fpostgresql.git

Do not define type for a property graph

Even though a property graph is defined in pg_class it does not
contain any rows by itself and need not have a type defined. Avoid
creating a type for it.
