The POSIX and UNIX standard requires this behavior.
See the man page for ways to increase the column size.
Comment 2 Mario Heininger 2004-10-14 04:07:16 EDT
Are you sure ? Maybe, when the Colum is tuncated at 8 chars it where
okay, but it displays only the UID, that is bad.

Comments from procps code:

The Open Group Base Specifications Issue 6 (IEEE Std 1003.1, 2004
Edition) requires that user and group names print as decimal numbers
if there is not enough room in the column, so tough luck if you don't
like it.

The UNIX and POSIX way to change column width is to rename it:
      ps -o pid,user=CumbersomeUserNames -o comm

The easy way is to directly specify the desired width:
      ps -o pid,user:19,comm
