Coverity has a nit about this:

*** CID 1616189:  Null pointer dereferences  (REVERSE_INULL)
/srv/coverity/git/pgsql-git/postgresql/src/backend/utils/adt/like.c: 206 in Generic_Text_IC_like()
200          * on the pattern and text, but instead call SB_lower_char on each
201          * character.  In the multi-byte case we don't have much choice :-(. Also,
202          * ICU does not support single-character case folding, so we go the long
203          * way.

206         if (pg_database_encoding_max_length() > 1 || (locale && locale->provider == COLLPROVIDER_ICU))
207         {
208             pat = DatumGetTextPP(DirectFunctionCall1Coll(lower, collation,
209                                                          PointerGetDatum(pat)));
210             p = VARDATA_ANY(pat);
211             plen = VARSIZE_ANY_EXHDR(pat);

I assume it would now be okay to take out "locale &&" here?
