<   is altered
<

< * -Allow the creation of indexes with mixed ascending/descending
<   specifiers

<   more evenly
< * -Allow sequential scans to take advantage of other concurrent
<   sequential scans, also called "Synchronised Scanning"
< * -Consider shrinking expired tuples to just their headers
< * -Allow heap reuse of UPDATEd rows if no indexed columns are changed,
<   and old and new versions are on the same heap page
< * -Reduce XID consumption of read-only queries
<     o -Turn on by default
<     o -Allow multiple vacuums so large tables do not starve small
<       tables
< * -Allow the pg_xlog directory location to be specified during initdb
<   with a symlink back to the /data location
< * -Allow buffered WAL writes and fsync
< * -Allow ORDER BY ... LIMIT # to select high/low value without sort or
<   index using a sequential scan for highest/lowest values
< * -Merge xmin/xmax/cmin/cmax back into three header fields
