Wyatt Alt 99adb1e621 feat: group a materialized view by the IVF partition of a vector column ...

Grouping near neighbours together, so an all-pairs comparison runs per
bucket instead of over the whole table, needs the partition an IVF index
assigns each vector.

`ivf_partition(column)` returns that partition, assigned by the centroids
and distance type of the IVF index on the column, the way the index path
does it: a cosine index assigns by L2 over unit vectors, a Hamming index
takes byte vectors, and a vector the assigner cannot place gets no bucket.
It is bound when the view is declared and again at every refresh; an index
retrain commits a new source version, so the next refresh regroups. A
column without an IVF index, or with two, is refused, and so is an index
whose segments were trained separately and carry different models or
whose metric does not fit the column's element type.
