I want to use my own image with PG 12. And everything seems to be fine. But here:
How to tell the operator what version of PG I have,
so that he does not write a parameter in the config
wal_keep_size – which appeared only in 13 and 14 versions?
Or another way to fix it?
I understand the reason - I’m sorry.
It turned out that the hosts in the cluster were with different versions of the PG.
Which of course shouldn’t be.
