[jira] [Updated] (SPARK-39162) Jdbc dialect should decide which function could be pushed down.

     [ https://issues.apache.org/jira/browse/SPARK-39162?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

jiaan.geng updated SPARK-39162:
-------------------------------
    Description: 
Regardless of whether the functions are ANSI or not, most databases are actually unsure of their support.
So we should add a new API into JdbcDialect so that Jdbc dialect could decide which function could be pushed down.
