pgsql: Report progress of CREATE INDEX operations
Report progress of CREATE INDEX operations
This uses the progress reporting infrastructure added by c16dc1aca5e0,
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.)

Had noticed, thanks. Just pushed a blind fix for that ...

I just noticed that valgrind is also complaining about
IndexVacuumInfo.report_progress being uninitialized in a couple of
callsites. Will fix early tomorrow.
