How to get UFS filesystem block size in FreeBSD

How to get UFS filesystem block size in FreeBSD using "dumpfs" utility

Code:
# dumpfs /var/ | grep "bsize"
bsize   16384   shift   14      mask    0xffffc000
maxbsize 16384  maxbpg  2048    maxcontig 8     contigsumsize 8
sbsize  2048    cgsize  16384   csaddr  3000    cssize  2048


Default UFS filesystem block size in FreeBSD is 16 K ( and from my reading, this is a decent value, but care needs to be taken when deploying Postgresql on FreeBSD - both UFS block size and Postgresql blocks should be at the same size).
