Michael Paquier 62074a3436 Provide statistics for hypothetical BRIN indexes
Trying to use hypothetical indexes with BRIN currently fails when trying
to access a relation that does not exist when looking for the
statistics.  With the current API, it is not possible to easily pass
a value for pages_per_range down to the hypothetical index, so this
makes use of the default value of BRIN_DEFAULT_PAGES_PER_RANGE, which
should be fine enough in most cases.

Being able to refine or enforce the hypothetical costs in more
optimistic ways would require more refactoring by filling in the
statistics when building IndexOptInfo in plancat.c.  This would involve
ABI breakages around the costing routines, something not fit for stable
branches.

This is broken since 7e534ad, so backpatch down to v10.
