Hello pgsql-hackers seems wrong list for such question.

So i decided to go with lower version. This is contrib modules. They can be shipped in separate package, postgresql10-contrib.x86_64 for example (in centos repo) > Second i tried to attempt to upgrade from 9.2.24 to 9.6.12,9.4,9.3 but its > failed with following error during Check Mode. > > could not load library "$libdir/pg_reorg": > ERROR: could not access file "$libdir/pg_reorg": No such file or directory > > Observation : In this case , pg_reorg is not present on both Source and > Target . But strange its failing. This is 3rd-party extension. Best way would be drop this extension on old cluster and perform upgrade. pg_reorg is abandoned for years, pg_repack is live fork if you need such tool. regards, Sergei
