Hi all,

I'm doing the pg_restore now in a 1.5TB file:

# ls -la

postgres postgres 1575324616939 Feb 20 13:55 devdb_0.sql

But, the restore has gone over 1.6 TB

# \l+

1639 GB

How is that even possible?

The dump itself doesn't contain index data.  It'll contain a line that says 'CREATE INDEX .....'
   The index is an on-disk entity that requires disk space, it's very common for a dump file and a restored database to very significantly in size.

pg_restore command:

/usr/pgsql-9.2/bin/pg_restore -d dbname --exit-on-error --jobs=4 --verbose devdb_0.sql

Cheers
