Phantom groups

["Carlos H. Reimer" <carlosreimer@xxxxxxxxxxxx>]

Hi,

I´m planning to migrate from 7.4 to 8.0.7 and I discovered some strange
behavior during migration.

pg_dump inserted GRANT to phantom groups. They do not exist in pg_group;

When the script created by pg_dump is processed by psql during restore,
these GRANTs produce a lot of errors.

How could I fix it?
