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
Well that would be the problem.
Did someone manually change --wal-segsize during initdb or pg_ctl init?
In any case that is not going to work. I'm assuming the 12 instance is
not in use at this time. If so I would do the initdb again after
clearing the data directory. Don't use the --wal-segsize, it will
default to 16MB. Then check with pg_controldata to make sure the correct
size is set.
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>
show for the setting Bytes per WAL segment: ?
