Provide the OR REPLACE option for CREATE TRIGGER. This is mostly straightforward. However, we disallow replacing constraint triggers or changing the is-constraint property; perhaps that can be added later, but the complexity versus benefit tradeoff doesn't look very good. Also, no special thought is taken here for whether replacing an existing trigger should result in changes to queued-but-not-fired trigger actions. We just document that if you're surprised by the results, too bad, don't do that. (Note that any such pending trigger activity would have to be within the current session.)

On 2nd of April 2019, Alvaro Herrera committed patch:

Report progress of CREATE INDEX operations
 
 
This uses the progress reporting infrastructure added by ,
adding support for CREATE INDEX and CREATE INDEX CONCURRENTLY.
 
There are two pieces to this: one is index-AM-agnostic, and the other is
AM-specific.  The latter is fairly elaborate for btrees, including
reportage for parallel index builds and the separate phases that btree
index creation uses; other index AMs, which are much simpler in their
building procedures, have simplistic reporting only, but that seems
sufficient, at least for non-concurrent builds.
 
The index-AM-agnostic part is fairly complete, providing insight into
the CONCURRENTLY wait phases as well as block-based progress during the
index validation table scan.  (The index validation index scan requires
patching each AM, which has not been included here.)
