Re: Setting up streaming replication with new server as master?

Hopefully, you set keep_wal_segments high enough that nothing has "expired"
from the master, if this is the case and if you set up the slave so it can
see those WAL segments, then your job is done. Just start the slave up and
it will process those transactions from the WAL segments that weren't part
of the pg_basebackup.

If, however, some of those WAL segments have disappeared off the master
server, then you get to perform this exercise all over again, i.e., a new
pg_basebackup.
