Huh, this seems really ugly, have you tried something like just
$ ps -o cmd:50,vsz,rss -C postmaster
CMD VSZ RSS
/pgsql/install/00head/bin/postmaster 51788 3992
postgres: writer process 51788 1060
postgres: wal writer process 51788 940
postgres: autovacuum launcher process 51924 1236
postgres: stats collector process 22256 896
