> A query which selects fields from a table will fail if we set the PostgresCatalog as default.
> Steps to reproduce:

> The problem is that Calcite will try to check first if there is a built-in function with that name that allows calls without parenthesis. Therefore it will query the {{FunctionCatalog}} for that function. The logic in {{org.apache.flink.table.catalog.FunctionCatalog#lookupFunction}} is such that it will call {{JdbcCatalog#getFunction}} in the end, which in case of {{AbstractJdbcCatalog}} throws {{UnsupportedOperationException}}.
