Although it may be good to note that command line length does not really play a role in this case, since "for" is a shell keyword and not an external command, so the length of the list should be more or less limited by memory...
There have been so many posts from AIX users (to name but a few O/S versions and variants and for the benefit of @jlliagre that includes many versions of SunOS/Solaris!) who hit this problem that I would love that the
for var in <open ended list> syntax would become a syntax error.
Somehow I knew that this thread was going to be fun.
Great posts @jgt, @alister and @Scrutinizer.

drop_role
DROP
ROLE(7) PostgreSQL 9.2.7 Documentation DROP ROLE(7)
NAME
DROP_ROLE - remove a database role
SYNOPSIS
DROP ROLE [ IF EXISTS ] name [, ...]
DESCRIPTION
DROP ROLE removes the specified role(s). To drop a superuser role, you must be a superuser yourself; to drop non-superuser roles, you must
have CREATEROLE privilege.
A role cannot be removed if it is still referenced in any database of the cluster; an error will be raised if so. Before dropping the role,
you must drop all the objects it owns (or reassign their ownership) and revoke any privileges the role has been granted. The REASSIGN OWNED
(REASSIGN_OWNED(7)) and DROP OWNED (DROP_OWNED(7)) commands can be useful for this purpose.
However, it is not necessary to remove role memberships involving the role; DROP ROLE automatically revokes any memberships of the target
role in other roles, and of other roles in the target role. The other roles are not dropped nor otherwise affected.
PARAMETERS
IF EXISTS
Do not throw an error if the role does not exist. A notice is issued in this case.
name
The name of the role to remove.
NOTES
PostgreSQL includes a program dropuser(1) that has the same functionality as this command (in fact, it calls this command) but can be run
from the command shell.
EXAMPLES
To drop a role:
DROP ROLE jonathan;
COMPATIBILITY
The SQL standard defines DROP ROLE, but it allows only one role to be dropped at a time, and it specifies different privilege requirements
than PostgreSQL uses.
SEE ALSO
CREATE ROLE (CREATE_ROLE(7)), ALTER ROLE (ALTER_ROLE(7)), SET ROLE (SET_ROLE(7))
