vacuum full analyze, but it took too long and it was using 100% of RAM, so I killed it. Now, Postgres won't start. I got:

The database is pretty small, it shouldn't be running out of disk space, so
vacuum full analyze must've created a lot of junk files. What's the proper way to fix this? I can't figure out how to use
pg_archivecleanup, I can't find the archive directory,
/var/lib/postgresql/14/main/pg_xlog doesn't exist. Here's everything in the folder:
sudo ls /var/lib/postgresql/14/main/ PG_VERSION pg_commit_ts pg_multixact pg_serial pg_stat_tmp pg_twophase postgresql.auto.conf base pg_dynshmem pg_notify pg_snapshots pg_subtrans pg_wal postmaster.opts global pg_logical pg_replslot pg_stat pg_tblspc pg_xact
This is a dev database, so in the worst case I can just delete everything. However, in case this happens in production, I'd like to know how else I can fix it.
