Here are a few patches related to attstattarget:
- 0001: Change type of pg_statistic_ext.stxstattarget, to match
attstattarget. Maybe this should go into PG16, for consistency?
- 0002: Add macro for maximum statistics target, instead of hardcoding
it everywhere.
- 0003: Take pg_attribute out of VacAttrStats. This simplifies some
code, especially for extended statistics, which had to have weird
workarounds.
