Hi PostgreSQL Admin, I am trying to find out if there is any step by step instruction to reconcile old data dir and upgraded data dir after using "-link" option to do an upgrade.
I ran this to do an upgrade from 11.5 to 12.1: pg_upgrade -d /hostname/pg/dev115/data -D /hostname/pg/dev121upg/data --link -b /pgdbadevbal800/pg/PostgreSQL-11.5/bin -B /pgdbadevbal800/pg/PostgreSQL-12.1/bin -p 1432 -P 2432 -v postgresdbad:dev115:pgdbadevbal800:> pwd /hostname/pg postgresdbad:dev115:pgdbadevbal800:> du -sh dev121upg 2.3G dev121upg postgresdbad:dev115:pgdbadevbal800:> du -sh dev115 22G dev115 My goal is to be able to do an in place upgrade from 11.5 to 12.1 using the same data dir "/hostname/pg/dev115/data". Without the "-link" option I need to double up the space usage for the instance. What is the easiest way to accomplish this task? Thanks so much for your help.
