[HACKERS] LIKE is still short some MULTIBYTE code

[Tom Lane]

I finished revising the LIKE operators back into an index-optimizable
form.  But I notice there is some non-multibyte-aware code that needs
to be fixed, specifically the pattern analysis routines in
src/backend/utils/adt/selfuncs.c:
        like_fixed_prefix
        regex_fixed_prefix
        like_selectivity
        regex_selectivity_sub
        regex_selectivity
I don't have time to work on this now, but perhaps someone else would
like to fix these...
