To see a list of bugs fixed since 15.2 came out, look at the commit log:
https://git.postgresql.org/gitweb/?p=postgresql.git;a=shortlog;h=refs/heads/REL_15_STABLE

Release 15.2 came out on 2023-02-09.

We don't have any information about yet undiscovered PostgreSQL bugs.

We believe that PostgreSQL 15.2 is a great and stable database, but we are biased.

Indeed.

One moderately objective way to see how stable a release branch is
is to count how many commits fix bugs in that branch but not any
older branch.  If a bug would be problematic for you but it also
appears in (say) v14 and v13, then choosing to use one of those
branches instead of v15 wouldn't have saved you.  Also, if a commit
goes back that far, it means that the bug escaped detection for
multiple years in production, which suggests that it is minor and/or
doesn't affect many people.  (I hasten to add that we do find some
bugs that are both old and serious.)

A quick review of commits since 15.2 says that practically all of the
ones that don't also affect v14 or before have to do with glitches in
new-in-15 features, such as the MERGE command.  Which is code you
wouldn't be using anyway if your application would be satisfied with
an older branch.  So I'd judge that 15 is pretty stable at this point,
and there is very little reason to prefer any older branch.

If you want to do your own analysis along these lines, the gitweb
interface isn't especially friendly for comparing commit logs of
different branches.  I'd suggest using our git_changelog script:

git clone https://git.postgresql.org/git/postgresql.git
cd postgresql
src/tools/git_changelog >../pg-revision-history

This produces output that collates matching commits in different
branches.
