Hi. Per Coverity.
Coverity raised the follow report: CID 1642824: (#1 of 1): Overflowed constant (INTEGER_OVERFLOW) 37. overflow_const: Expression pattern_len - 1ULL, where pattern_len is known to be equal to 0, underflows the type of pattern_len - 1ULL, which is type unsigned long long. This is because the function *pg_mbstrlen* can return zero. And the comment is clear, *just in case there are MB chars*. patch attached. best regards, Ranier Vilela
