* Commit 3048898e dropped -ING from PHJ wait event names. Update the corresponding barrier phases names to match. * Rename the "DONE" phases to "FREE". That's symmetrical with "ALLOCATE", and names the activity that actually happens in that phase (as we do for the other phases) rather than a state. The bug fixed by commit 8d578b9b might have been more obvious with this name. * Rename the batch/bucket growth barriers' "ALLOCATE" phases to "REALLOCATE", a better description of what they do. * Update the high level comments about phases to highlight phases are executed by a single process with an asterisk (mostly memory management phases). No behavior change, as this is just improving internal identifiers. The only user-visible sign of this is that a couple of wait events' display names change from "...Allocate" to "...Reallocate" in pg_stat_activity, to stay in sync with the internal names.
