From ab0dfc961b6a821f23d9c40c723d11380ce195a6 Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Tue, 2 Apr 2019 15:18:08 -0300 Subject: [PATCH] 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.)
