Subject: Use <unnamed> for name of unnamed portal's memory context
X-Git-Tag: REL_14_BETA1~1693
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=728d4bc16b79dea0dd6d540aa5c55a84ac722a09;p=thirdparty%2Fpostgresql.git

Use <unnamed> for name of unnamed portal's memory context

Otherwise just printing an empty string makes the memory context debug
output slightly confusing.
