Unused disk space is released by VACUUM FULL. If I understand your
situation correctly, I'd recommend temporarily adding some more disk
space or moving some data to another partition to allow the postmaster
to startup. Then you can reclaim some disk space using VACUUM FULL
and/or REINDEX. In the future, run VACUUM more frequently (and perhaps
bump max_fsm_pages).
