pg_dump/pg_restore fail for TAR_DUMP and CUSTOM_DUMP from v94/v95/v96to v11/master.

Hi,

I got a failure in pg_dump/pg_restore as below:

pg_dump/pg_restore fails with 'ERROR: schema "public" already exists' for TAR_DUMP and CUSTOM_DUMP from v94/v95/v96 to v11/master.

-- Take pg_dump in v94/v95/v96:

[prabhat@localhost bin]$ ./pg_dump -f /tmp/tar_dump_PG94.tar -Ft postgres -p 9000

[prabhat@localhost bin]$ ./pg_dump -f /tmp/custom_dump_PG94.sql -Fc postgres -p 9000

-- Try to restore the above dump into v11/master:

[prabhat@localhost bin]$ ./pg_restore -F t -U prabhat -d db3 -p 9001 /tmp/tar_dump_PG94.tar
