PostgreSQL compatibility: log(0.0::float8) should error, not return -inf #22261

@Dandandan

Description

@Dandandan

Split out from #22247.

Mismatch

log(0.0::float8) should error, not return -inf.

SELECT log(0.0::float8);

PostgreSQL:

ERROR: cannot take logarithm of zero

DataFusion:

-inf

Expected behavior

For PostgreSQL-compatible SQL semantics, DataFusion should either match PostgreSQL's result or raise the same class of domain/semantic error.
