0001-Change-type-of-pg_statistic_ext.stxstattarget.patch (text/plain) patch 0001
0002-Add-macro-for-maximum-statistics-target.patch (text/plain) patch 0002
0003-Take-pg_attribute-out-of-VacAttrStats.patch (text/plain) patch 0003

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.
