Do we need to add anything related to https://github.com/pingcap/tidb/issues/49508 ?

And https://github.com/pingcap/tidb/issues/45506 seems to suggest that more functions might be supported.

[dveeden]

Looking at getFuncCallDefaultValue() it looks like these are supported:

• CURRENT_TIMESTAMP(),
• CURRENT_DATE()
• NEXTVAL()
• RAND()
• UUID()
• UUID_TO_BIN()
• DATE_FORMAT()
• REPLACE()
• UPPER()
• STR_TO_DATE()

Some of these (REPLACE(), UPPER(), ...) are only supported with specific arguments.

• REPLACE, UPPER, STR_TO_DATE supported as this PR, and the related issue: https://github.com/pingcap/tidb/issues/50936
