Thank you for your response! I really appreciate it.
I don't know why I couldn't make it well. I got tired after doing many approaches.
I tried 3 approaches for this :
Approach 1 :
I tried with a new instance installed postgresql version 13 then created some test DB, and inserts a few data into a table. Then update version 15, I can see all data - Succeed
Approach 2 :
I tried with a new instance installed postgresql version 13 then created an Image of this instance and launched a new instance using this image (AMIs).
Then update version 15, I can see all data of version 13 - Succeed
Approach 3 :
I launch a new instance using the latest image of our postgresql instance. Then update version 15, it shows error - Failed
=> Reasons or error :
/usr/lib/postgresql/15/bin/pg_upgrade: symbol lookup error: /usr/lib/postgresql/15/bin/pg_upgrade: undefined symbol: PQmblenBounded
- Always get PQmblenBounded error whenever I try to execute postgresql binary.
Information:
- I'm using Postgresql 13.6 which is hosted on Ubuntu ( 18.04.6 LTS, Codename : bionic)
- DB Data is more than 650 GB so I can't go with pgdump option
You suggested that I fix a dynamic linker but I always get some errors and finally I am stuck in a loop of these solutions.
If I try to fix one another problem come up.
Please suggest steps to complete this task.I'm writing to you as a last option, I stopped searching on google.
Thanks & Regards
Dippu
