Thanks for taking the time to reply, and pinning to a specific commit
is in line with some of the information that I found, in particular
in the FreeBSD forums. But that leads to another question.

I haven't done a lot with git in some time, but I am familiar with the
basics. I seem to recall that in order to identify a directory as a
git repo there should be a .git directory and a few other git related
items. I do not see any of that in any of the ports directories. For
instance:

 ls /usr/local/poudriere/ports/default/databases/postgresql15-server
 total 259
 drwxr-xr-x     3 root  wheel     13 May 16 13:07 ./
 drwxr-xr-x  1085 root  wheel   1086 Jun 24 20:19 ../
 -rw-r--r--     1 root  wheel    801 May 16 13:07 Makefile
 -rw-r--r--     1 root  wheel    187 May 16 13:07 distinfo
 drwxr-xr-x     2 root  wheel     18 May 16 13:07 files/
 -rw-r--r--     1 root  wheel   1238 Mar  1 11:12 pkg-descr
 -rw-r--r--     1 root  wheel    482 Mar  1 11:12 pkg-install-server
 -rw-r--r--     1 root  wheel  58816 Mar  1 11:12 pkg-plist-client
 -rw-r--r--     1 root  wheel  10763 Mar  1 11:12 pkg-plist-contrib
 -rw-r--r--     1 root  wheel    979 Mar  1 11:12 pkg-plist-plperl
 -rw-r--r--     1 root  wheel   1389 Mar  1 11:12 pkg-plist-plpython
 -rw-r--r--     1 root  wheel    197 Mar  1 11:12 pkg-plist-pltcl
 -rw-r--r--     1 root  wheel  89992 May 16 13:07 pkg-plist-server

Is that the right tree, or should I be looking elsewhere? I'm just
not sure where run the git commands from. If I knew that I might
could figure the rest out from there.

Yeah, my intent here is to do some simple a/b testing prior to a
production upgrade. I think the easiest option is to just create
two jails, one at the current level, and one at 15.6. I just need to
figure out the pinning part and I'm probably good.
