But createuser/dropuser are a real problem, because they certainly could be mistaken for system-level utilities.
I proposed something along those lines [1] to fix this historical mistake but we didn't reach a consensus. createuser/dropuser could be a candidate to removal because it is easily replaced by psql -c "command here" like Simon said. If we go to this road, other binaries (that are just a wrapper around an SQL command) could be removed too (such as createdb, dropdb, clusterdb and reindexdb).
