query against the partition information, without having to read

for UDFs that take only constant inputs, as this interface will only
be useful if we can evaluate the constant UDF at planning time.
Any function defined to use this interface that is not evaluated
at planning time by the constant folding rule will be querying
the storage plugin for meta-data for each record processed.
Be sure to check the query plans to see that this expression has already
been evaluated during planning if you write UDFs against this interface.
