How do I check the fillfactor on the table, please?

its in the field reloptions in pg_class.   so...

    select reloptions from pg_class where relname='tablename';

if tablename is non-unique, you'll need to qualify that with the OID of the namespace (aka schema).

My largest table is 50 GB in size; when I pg_dump it, and then
pg_restore it, it becomes 100 GB in size.

How do I pg_restore it so that it is 50 GB in size?  Is it a setting
to pg_dump or to pg_restore?


are you truncating the table before restoring, or is this a restore into a new database, or what?
