ps axjf

/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
 \_ postgres: logger process   
 \_ postgres: checkpointer process   
 \_ postgres: writer process   
 \_ postgres: wal writer process   
 \_ postgres: autovacuum launcher process   
 \_ postgres: stats collector process   
 \_ postgres: bgworker: pglogical supervisor   

AFAIK the wal writer process.
