Is it normal for a parallel pg_restore to result in locks? Will these usually resolve themselves?

The restore is running with 16 jobs into an RDS instance and at the moment pg_locks has about 243 AccessShareLock, 35 ExclusiveLock, 24 AccessExclusiveLock, and 8 ShareLock...

Will these just resolve as queries finish, or is it a concern? The restore has been running a long time.

pg_restore command:

time pg_restore \
--host=${HOST} \
--user=postgres \
--format=directory \
--dbname=${DB} \
--jobs ${JOBS} \ 

Where JOBS here 16.
