I strongly disagree. The BOM provides a useful and standard way to
differentiate UTF-8 encoded text files from the random pile of encodings
that any given file could be.
On many platforms (including all Windows versions) the default system
text encoding for 8-bit text is not UTF-8. On such systems, a BOM in a
UTF-8 file allows a program/editor to reliably work out that it's UTF-8
and treat it as such, rather than mangling it by interpreting it as the
local system encoding.
psql should accept UTF-8 with BOM.
