Modified files:
	src/backend/commands: Tag: REL7_4_STABLE copy.c 

Log message:
	Don't use %s-with-precision format spec to truncate data being displayed
	in a COPY error message.  It seems that glibc gets indigestion if it is
	asked to truncate strings that contain invalid UTF-8 encoding sequences.
	vsnprintf will return -1 in such cases, leading to looping and eventual
	memory overflow in elog.c.  Instead use our own, more robust pg_mbcliplen
	routine.  I believe this problem accounts for several recent reports of
	unexpected 'out of memory' errors during COPY IN.
