Re: Truncate on pg_dump / pg_restore

You can, assuming you start off with a pg_dump in custom format (use -Fc).
You can use pg_restore's -l option to drop out the list contents of the
archive, and then comment out whatever you do not want restored:

pg_dump -Fc ....... > your_db.dump

pg_restore -l your_db.dump > your_db.list

# edit your_db.list and comment out whatever you don't need (or reorder if
needed)

# use your_db.list for the actual restore:

pg_restore -L your_db.list your_db.dump
**

Look at the examples on:
