Caican Cai updated CALCITE-6259:
--------------------------------
Description:
The implementation of the Log library operator does not match the actual
dialect behavior.
For example, when log10(0) returns null in mysql and spark, but log10(0)
returns error in postgres, neither is calcite's -Intity
{code:java}
postgres=# select log10(0);
ERROR: cannot take logarithm of zero
postgres=# select log(2,0);
ERROR: cannot take logarithm of zero
{code}
