I have a fairly busy primary that I put a symlink in to move pg_xlog
over to another I/O subsystem. I was going to build a standby with
pg_basebackup running the command from the standby host. I thought
maybe I could put the symlink in on the new standby, but no go:
"pg_basebackup: directory "/database/test.basebackup/" exists but is not
empty" as documented. Is the only way to do this to "fix" it up after
the restore? I want to use the "-x" option in order to get the WAL
during the backup. Just curious, my guess is I'll have to build the
stby from a intermediate file. TIA.

pg_basebackup has a --waldir or --xlogdir (depending on version) option
for this, analogous to initdb.
