Then KDevelop is wrong. It appears that KDevelop's "makefile" editing
mode doesn't properly handle backslash continuations.

The _RULE_ does end with it, because the rule includes all the recipe
lines that appear after the target. But variable/function invocations
cannot span different lines of a recipe. They all must be contained
within the same logical line, as I mentioned before.
This is trivial to try out for yourself (like most things in make); just
write a simple makefile:
$ cat > Makefile <<EOF
all:
$(info hello \
there)
$(info hello
there)
$ make
hello there
Makefile:2: *** unterminated call to function 'info': missing ')'. Stop.
So the backslashed version (same logical line) works but the
non-backslashed version (different logical lines) fails. I'm not sure
why the linenumber is wrong though... hm...

It is definitely needed. As I've said, it is not possible for a single
variable or function reference to span multiple logical lines.
If you want to do this you have to use define/endef to create a variable
that contains newlines, then use the variable in the recipe; see example
below.
I'm really not at all sure why you're using $(info ...) here... it won't
actually do anything if you do that.
define RUN_PARALLEL
$(eval LET_RUN_DATA_EXPORT1_PARALLEL::=)@$(RM)
'$(RESULT_SQL_DATABASE_NOTIFICATION8)'
$(DATABASE_CLI) -c \
'$(SQL_SELECT_START)_parallel1 where static = 0 $(SQL_SELECT_END)' \
'$(DATABASE_NAME)' \
> '$(RESULT_FUNCTIONS_WITH_PREFIX_PARALLEL)' \
&& $(TOUCH) '$(RESULT_SQL_DATABASE_NOTIFICATION8)'
endef
$(RESULT_FUNCTIONS_WITH_PREFIX1_PARALLEL) \
$(RESULT_SQL_DATABASE_NOTIFICATION8): \
initialise_database \
$(RESULT_SQL_DATABASE_NOTIFICATION4)
$(info $(if $(LET_RUN_DATA_EXPORT1_PARALLEL),$(RUN_PARALLEL)))
