RE: Upgrade check failed from 11.5 to 12.1

Thanks Adrian.

This is what I am seeing.

postgresdbad:dpoc:pgdbadevbal800:> pg_controldata -D /hostname/pg/dev12upg/data | grep -i "Bytes per WAL segment"

Bytes per WAL segment: 131072

postgresdbad:dpoc:pgdbadevbal800:> pg_controldata -D /hostname/pg/dpoc/data | grep -i "Bytes per WAL segment"

Bytes per WAL segment: 16777216

Well the default is 16MB so you should not have to set it.

What does:

pg_controldata -D <11.5 data dir>

pg_controldata -D <12.1 data dir>
