…functions after using persistent functions Revert the changes of #17646 made in Branch 2.1, because it breaks the build. It needs the parser interface, but SessionCatalog in branch 2.1 does not have it. ### What changes were proposed in this pull request? The session catalog caches some persistent functions in the `FunctionRegistry`, so there can be duplicates. Our Catalog API `listFunctions` does not handle it. It would be better if `SessionCatalog` API can de-duplciate the records, instead of doing it by each API caller. In `FunctionRegistry`, our functions are identified by the unquoted string. Thus, this PR is try to parse it using our parser interface and then de-duplicate the names. ### How was this patch tested? Added test cases. Author: Xiao Li <[email protected]> Closes #17661 from gatorsmile/compilationFix17646.
