Streaming replication: replicant server not starting (9.4.4, Win2008) - Mailing list pgsql-general

I've inherited a PG 9.4.4 install on Win 2008 that I'm wanting to
stream from (abt 80Gb on disk).  Everything seems to be working from
the "master" side.

I have an AMI of the master host (a vmware instance in our soon to
close data centre) that has been spun up in AWS (replicant).  In it's
"default" configuration (ie, exactly the same as master) it worked
fine.

I ran pg_basebackup on the master (from memory- details on work pc):
pg_basebackup -D "e:\\mybasebackup\\" -F t -R -X f -z -c fast \
 -h <ip_addr> -U <rep_user>

Base backup is created fine.  I've copied it up to AWS and extracted it
into the correct location (after ensuring it is empty) on the replicant
windows host (tar -xzvf base.tgz from a linux box with the pg data
drive mounted).  File metadata is changed during the extraction (ie,
file timestamps- could this possibly be an issue?) but permissions on
the win2008 replicant host have been set & double checked.

When I try to start the pg server on replicant, the log streaming from
master works (and keeps working till the server is rebooted), but the
server can't start for some reason.

Copy of pg log file on replicant:

2018-01-30 17:18:08 AWST FATAL:  the database system is starting up

The last line is repeated for about a minute till it gives up.  It
leaves behind a bunch of processes that keep streaming log files as
master creates new wal records.  This keeps going till the replicant
box is rebooted (easiest way to clean up the processes and free up port
5432).

I can keep rebooting the replicant host and on retrying to start the pg
server, it will apply any new wal files that have been streamed, then
fail to start the server but keep streaming again.

The Windows service start command for PG: 

"C:\Program Files (x86)\PostgreSQL\9.4.4\bin\pg_ctl.exe" runservice -N
"postgresql-9.4" -D "E:\PostgreSQL\9.4.4\data" -w

Config files:

Replicant postgresql.conf (essentially a copy from master with minimal
changes):

dynamic_shared_memory_type = windows
wal_level = archive
max_standby_streaming_delay = 30s
wal_receiver_status_interval = 30s
log_line_prefix = '%t '

log_min_duration_statement = 500
log_line_prefix = '%t '

replicant recovery.conf:

standby_mode = 'on'
primary_conninfo = 'host=<master_ip> user=<rep_user>
password=<don't_tell> connect_timeout=10 application_name=replicant_3'
primary_slot_name = 'replicant_3'
recovery_min_apply_delay = 10
#restore_command = 'copy
"e:\\PostgreSQL\\9.4.4\\basebackup\\wal_archive\\%f" "%p" ' 
trigger_file = 'recovery_done.txt'

The restore_command was uncommented at first and worked fine. All new
updates now are provided by streaming.

Any ideas?  I'm tearing my hair out with this. The boxes are about as
identical as you can get, apart from the fact that one is running on
VMware and the other in AWS.

Thanks,
