* [PATCH v49 4/7] Fix a few problems in index build progress reporting.
@ 2026-03-27 15:50 Álvaro Herrera <[email protected]>
  0 siblings, 0 replies; 21+ messages in thread

From: Álvaro Herrera @ 2026-03-27 15:50 UTC (permalink / raw)

First, index_build() should not update the progress when being driven by
REPACK, because the progress reporting infractructure cannot handle status of
two commands at the same time. So far, REPACK with the CONCURRENTLY option
neglected this problem altogether, but even the existing REPACK wasn't
consistent enough: even if the 'progress' variable in repack_index() was
false, it didn't pass the value to index_build().

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to
PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls
finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which
does the same thing.
