> A query which selects fields from a table will fail if we set the
> PostgresCatalog as default.
> Steps to reproduce:
> # Create postgres catalog and set it as default
> # Create any table (in any catalog)
> # Query that table with {{SELECT field FROM t}} (Important it must be a
> field name not '{{*}}'
> # The query will fail
> Stack trace:
> {code}

> 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}}.
