Thread: pgsql: Fix overflow in parsing of positional parameter
Fix overflow in parsing of positional parameter Replace atol with pg_strtoint32_safe in the backend parser and with strtoint in ECPG to reject overflows when parsing the number of a positional parameter. With atol from glibc, parameters $2147483648 and $4294967297 turn into $-2147483648 and $1, respectively.
