<para>

Fix cases where a logical replication

slot's <structfield>restart_lsn</structfield> could go backwards

(Masahiko Sawada)

<ulink url="&commit_baseurl;15dc1abb1">&sect;</ulink>

</para>

<para>

Previously, restarting logical replication could sometimes cause the

slot's restart point to be recomputed as an older value than had

previously been advertised

in <structname>pg_replication_slots</structname>. This is bad,

since for example WAL files might have been removed on the basis of

the later <structfield>restart_lsn</structfield> value, in which

case replication would fail to restart.
