It's normal to have one postmaster process with three (or more) children, eg

tgl 603 0.0 0.3 39924 3576 ? S Apr26 0:00 postmaster -i -F
tgl 607 0.0 2.5 40060 26012 ? S Apr26 0:07 postgres: writer process
tgl 608 0.0 0.0 11936 708 ? S Apr26 0:00 postgres: stats buffer process
tgl 609 0.0 0.0 11172 916 ? S Apr26 0:00 postgres: stats collector process

If you're using a process-viewing tool that calls them all "postmaster",
get a better tool. Even plain old "ps" can do better than that.
(The above is "ps auxww" output.)
