The reconnection test assumed that a restarted walsender would always
have a different PID from the previous one. On some platforms, however,
PIDs can be reused quickly, causing the test to time out even though
pg_recvlogical has successfully reconnected.
This issue was reported by buildfarm member fairywren:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=fairywren&dt=2026-07-30%2009%3A58%3A12
Fix this by waiting for the server log message indicating that the
logical replication slot has been acquired again, rather than relying on
a PID change.
Backpatch to v19, where the affected reconnection test was introduced by
commit d89b1d8175.
