Subject: When positioned before the start of a ResultSet issuing relative(0)
X-Git-Tag: REL7_4_8~20
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e1d55f79177adc4f5fe3eb27a5a5e8a7e15eed56;p=thirdparty%2Fpostgresql.git

When positioned before the start of a ResultSet issuing relative(0)
results in an exception being thrown when it really should be a
no-op.
