mohayu22 opened a new issue, #791:
URL: https://github.com/apache/age/issues/791
**Describe the bug:**
The server crashes with Segmentation Fault error whenever the _value_
property of a Node or Edge is set to `rand()` or `pi()`
```
Program received signal SIGSEGV, Segmentation fault.
0x00005650823d9abb in datumTransfer (value=4592508940796821504,
typByVal=typByVal@entry=false, typLen=-1) at datum.c:192
192 if (!typByVal && typLen == -1 &&
```
**How to produce the error?**
```
SELECT * from cypher('demo', $$
MATCH (n)
SET n.value = rand()
RETURN n
$$) as (result agtype);
```
And
```
SELECT * from cypher('demo', $$
MATCH (n)
SET n.value = pi()
RETURN n
$$) as (result agtype);
```
**Important:**
```
/*
* Check for openCypher functions that are directly mapped to PG
* functions. We may want to find a better way to do this, as there
* could be many.
*/
if (pg_strcasecmp(name, "rand") == 0)
funcname = SystemFuncName("random");
else if (pg_strcasecmp(name, "pi") == 0)
funcname = SystemFuncName("pi");
else if (pg_strcasecmp(name, "count") == 0)
funcname = SystemFuncName("count");
```
**Additional context:**
Using `rand() + 0` or `pi() + 0` resolves the issue and allows the program
to function properly.
**Environment:**
- PostgreSQL 11.18
- Apache Age (master branch)
