ERROR: could not open file "pg_tblspc/ issue with replication setup.

Hi,

While testing for a feature I got this tablespace related error while
running script.
The Issue is not reproducible everytime, but If I am running the same set
of commands after 2-3 runs I am able to reproduce the same error.

--first run - pass
# master slave setup
+ mkdir /tmp/test_bkp/tblsp01
+ ./psql postgres -p 5432 -c 'create tablespace tblsp01 location
'\''/tmp/test_bkp/tblsp01'\'';'
CREATE TABLESPACE
+ ./psql postgres -p 5432 -c 'create table test (a text) tablespace
tblsp01;'
CREATE TABLE
#cleanup

--next
#master-slave setup
+ mkdir /tmp/test_bkp/tblsp01
+ ./psql postgres -p 5432 -c 'create tablespace tblsp01 location
'\''/tmp/test_bkp/tblsp01'\'';'
CREATE TABLESPACE
+ ./psql postgres -p 5432 -c 'create table test (a text) tablespace
tblsp01;'
ERROR: could not open file "pg_tblspc/16384/PG_13_202004074/13530/16388":
No such file or directory

Attaching command and script which help to reproduce it.
[edb(at)localhost bin]$ while sh pg_tblsp_wal.sh; do :; done

Thanks & Regards,
