My database is total around 100 gigs of data, and I have 50 gigs free on
the volume, yet I get this error message. It was a simple join. Is there
a way to see more information on why I got this error?

Hash-joins can use a lot of space on temp files. Try running the query and at the same time monitor disk usage from the database temp/ directory ($PGDATA/dboid/temp/).
