Summary
Closes #4916
CREATE FUNCTION ... CALLED ON NULL INPUTfalls back toexp.Commandfor every dialect, losing the AST representation. This PR aims to fix it by addingCalledOnNullInputPropertyso the statement parses correctly asexp.Create.The parser hook is added to the
baseparser rather than scoped to a single dialect (original issue reports Snowflake). This fixes Snowflake, Postgres, BigQuery, and the basesqlglotdialect. Added tests to cover Snowflake, Postgres and extendedidentity.sqlto validate the defaultsqlglotdialect.
