Fix test instability

alvherre · alvherre · commit 59be1c942a47 · 2022-07-29T12:50:47.000+02:00
On FreeBSD, the new test fails due to a WAL file being removed before the standby has had the chance to copy it. Fix by adding a replication slot to prevent the removal until after the standby has connected.
