⏸ On hold — not being ported right now

Parked in pr_sources.on_hold: not vetoed, just waiting on something (a follow-up PR, a decision). releasy run skips them, and anything that depends on one reports as blocked. Comment here to put one back in work (or take it off on_hold in the session file) and it ports on the next run.

Is there any particular reason why #2141 belongs to auto-grp-pr-2141? Seems like it can be a standalone PR

[zvonand]

#2154 must be excluded in favor of ClickHouse#90740.

and #2268 becomes a standalone PR.

[zvonand]

#2038 does not need to be here at all, it is to be ported manually. remove it.

#2148 is a cherry-pick of ClickHouse#104251, as I understand, must be in upstream version already.

[ianton-ru]

I think need to port
#2183
#2271
#2249
#2197
I did not set port-antalya on these PRs, because there is a chance that PRs would not be required in future versions because of alternative upstream implementations or accepting my PRs in upstream. But this is not happened in 26.8.
Added label port-antalya on these PRs.
