Add resource statistics reporting to ANALYZE VERBOSE.
Previously, log_autovacuum_min_duration utilized dedicated code forlogging resource statistics, such as system and buffer usage duringautoanalyze. However, this logging functionality was not utilized byANALYZE VERBOSE.This commit adds resource statistics reporting to ANALYZE VERBOSE byreusing the same logging code as autoanalyze.Author: Anthonin BonnefoyReviewed-by: Masahiko SawadaDiscussion:https://postgr.es/m/CAO6_Xqr__kTTCLkftqS0qSCm-J7_xbRG3Ge2rWhucxQJMJhcRA%40mail.gmail.com
