Thread: Question on upgrading postgresql from 10.7 to 11.5
Hello,
I am trying to upgrade my PG instance from 10.7 to 11.5.
I got an error in doing so. Any idea what I am missing?
Example: pg_upgrade -d /hostname/pg/dpoc/data -D /hostname/pg/dpoc115/data -b /hostname/pg/PostgreSQL-10.7/bin -B /hostname/pg/PostgreSQL-11.5/bin -p 5432 -P 9432 -c -v
Error message:
old and new pg_controldata WAL segment sizes are invalid or do not match
Failure, exiting

It looks like you used "initdb --wal-segsize" for the 11.5 cluster using a value different from the one that were used in your 10.7 cluster (probably 16MB). You can check the value for each using "SHOW wal_segment_size". You have to recreate a new pg11 data directory using the same value as the 10.7 one. While at it, you should update the pg11 binary to the latest minor version, 11.6.
Thanks! I was misled by "pg_controldata" keyword and totally ignored the WAL segment size variable. Much appreciated for your help. -----Original Message----- From: Julien Rouhaud [mailto:rjuju123@gmail.com] Sent: Wednesday, December 25, 2019 10:36 AM To: Lu, Dan <Dan.Lu@sig.com> Cc: pgsql-general@postgresql.org Subject: Re: Question on upgrading postgresql from 10.7 to 11.5 On Wed, Dec 25, 2019 at 3:42 PM Lu, Dan <Dan.Lu@sig.com> wrote: > > Hello, > > I am trying to upgrade my PG instance from 10.7 to 11.5. > > I got an error in doing so.
