pg_restore fails with ERROR: could not create directory "pg_tblspc/16400/PG_11_201809051/16403": Invalid argument

Trying to migrate PG9.1 data to PG11.5 I did initdb using the following command. "\bin\initdb.exe" --locale="English_Malaysia.1252" -D "\pgupgrade" -U --pwfile Command output: The files belonging to this database system will be owned by user "Administrator". This user must also own the server process. The database cluster will be initialized with locale "English_Malaysia.1252". The default database encoding has accordingly been set to "WIN1252". The default text search configuration will be set to "english". Part of pg_upgrade the following is failing: command: "/pg_restore" --port 50432 --username --create --exit-on-error --verbose --dbname template1 "pg_upgrade_dump_16388.custom" >> "pg_upgrade_dump_16388.log" 2>&1 pg_restore: connecting to database for restore pg_restore: creating DATABASE "xyz" pg_restore: [archiver (db)] Error while PROCESSING TOC: pg_restore: [archiver (db)] Error from TOC entry 4037; 1262 16388 DATABASE xyz pg_restore: [archiver (db)] could not execute query: ERROR: could not create directory "pg_tblspc/16400/PG_11_201809051/16403": Invalid argument Command was: CREATE DATABASE "xyz" WITH TEMPLATE = template0 ENCODING = 'UTF8' LC_COLLATE = 'English_Malaysia.1252' LC_CTYPE = 'English_Malaysia.1252' TABLESPACE = "xyz"; Can anyone tell me the possible cause of failure? Is it encoding issue? in first case DB was initialized with win1252 but during pg_restore it is running with utf8. Also can you tell me how can I troubleshoot this error further as I am not getting what is "invalid argument" here?
