Tom Lane f261ad241d Fix possible buffer overrun in contrib/pg_trgm. ... 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.		2014-01-13 13:07:23 -05:00
