Subject: Reduce lock levels of CREATE TRIGGER and some ALTER TABLE, CREATE
 RULE actions. Avoid hard-coding lockmode used for many altering DDL commands,
 allowing easier future changes of lock levels. Implementation of initial
 analysis on DDL sub-commands, so that many lock levels are now at
 ShareUpdateExclusiveLock or ShareRowExclusiveLock, allowing certain DDL not
 to block reads/writes. First of number of planned changes in this area;
 additional docs required when full project complete.
