I think that makes sense.  I couldn't assess by looking at tests for
various functions listed on 9.25. System Information Functions whether
there is some established practice about adding tests for them and/or
about where to put them.

For this particular set of functions, insert.sql may be a good place as it
has many tests involving multi-level partitioned tables.
