Today I was busy rebasing my Greenplum-related Extendable SMGR
patches on Cloudberry, and I faced some conflicts.
While resolving them I noticed code & comments inconsistency in smgr.c
in smgrtruncate function, which tracks down to
c5315f4f44843c20ada876fdb0d0828795dfbdf5. In this commit,
smgr_fsm_nblocks & smgr_vm_nblocks fields were removed, however
comments were not fixed accordingly.
So i suggest to fix this, PFA
