PostgreSQL version upgrade

[rubenskuhl]

Any concerns or pitfalls upgrading PostgreSQL 12 to a newer one in an IRRd 4.4.4 environment ?
For now, the only thing I mapped is that P12 used MD5 and will require password reset in a newer version.
IRRd mentions "Versions 9.6, 11.16, 13.7, 15.0" - Should I not got beyond 15 ? 16 is the one used in newer distributions, while 17 is available. Isn't 14 tested/recommended ?

There are no known issues with newer versions of PostgreSQL. Perhaps some of the configuration advice could be revisited, like whether setting random_page_cost different from default still applies. The specific list comes from the version matrix in CI configuration which is run before release. For brevity, I don't test every intermediate version of all dependencies there.
