Allow for the possibility that folding a string to lower case makes it longer (due to replacing a character with a longer multibyte character). This doesn't change the number of trigrams that will be extracted, but it does affect the required size of an intermediate buffer in generate_trgm(). Per bug #8821 from Ufuk Kayserilioglu. Also install some checks that the input string length is not so large as to cause overflow in the calculations of palloc request sizes. Back-patch to all supported versions. |
