PostgreSQL compatibility: power(0.0::float8, -1.0::float8) should error, not return infinity #22272

@Dandandan

Description

@Dandandan

Split out from #22247.

Mismatch

power(0.0::float8, -1.0::float8) should error, not return infinity.

SELECT power(0.0::float8, -1.0::float8);

PostgreSQL:

ERROR: zero raised to a negative power is undefined

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.
