Check for the max walsize allocated in postgresql.conf and also check on checkpoint completion target default is 0.9 this says how frequent the checkpoint can be applied that adds to wal lan generation.
First do a table level vaccuum and see what's causing it to write more wal files.

Hi All
When we are running vacuumdb for our database of 1.5TB it is generating approximately 60GB of WAL files? Any way we can reduce this WAL file generation?
