pg_strtoint32() int32 pg_strtoint32 ( const char *  s ) Return an input string converted to a signed 32 bit integer. Allows any number of leading or trailing whitespace characters. Will throw ereport() upon bad input format or overflow. Returns On error return PG_INT32_MAX; Note Accumulate input as a negative number, to deal with two's complement representation of the most negative number, which can't be represented as a positive number.
