Thread: FATAL: could not receive timeline history file from the primary server: ERROR: could not open file "pg_wal/0000000x.history": No such file or directory

hello everyone, I want to install a two-node streaming replication with postgresql version 11, but I'm getting this error when starting the service of my slave node. Can you support me? I couldn't find the solution.

It seems like that the stanby is on TLI=1 and the primary is on 2 or
greater (call it n).  In that case, at replication start, the standby
requests to the primary every history (0000000n.history) files from
TLI=2 to TLI=n if the standby doesn't have.

Thus, the message means 0000002.history has been somehow removed in
pg_wal of the primary, but I'm not sure how come it happened.

If you did remove some history files on primary, do not remove them
for between the TLIs of primary and standby.

> slave node has recovery.conf file and include primary_con_info informations.

regards.
