Re: [PROPOSAL] VACUUM Progress Checker.

Hello,
>Your current design completely misses the time taken to scan indexes, which
is significant.
I tried to address this issue in the attached patch.
The patch calculates index scan progress by measuring against scanned pages
in LVRelStats. It checks for a change current page being scanned and
increments the progress counter. When counter reaches scanned pages number
in LVRelStats, progress is 100% complete. For now the progress is emitted as
a warning (so no config changes needed to see progress)
Thoughts?
