Subject: Move comment about test slightly closer to test.
X-Git-Tag: REL_10_BETA1~977
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8a815e3fc318b441a5e8a37e4129660d81e1e012;p=thirdparty%2Fpostgresql.git

Move comment about test slightly closer to test.

The addition of a TestForOldSnapshot() call here has made the
referent of this comment slightly less clear, so move the comment
to compensate.
