pgsql: Fix remote position tracking in logical replication

Fix remote position tracking in logical replication

We need to set the origin remote position to end_lsn, not commit_lsn, as
commit_lsn is the start of commit record, and we use the origin remote
position as start position when restarting replication stream. If we'd
use commit_lsn, we could request data that we already received from the
remote server after a crash of a downstream server.
