$ make -s -C src/test/recovery/ check PROVE_TESTS=t/039*
t/039_end_of_wal.pl .. 4/?
#   Failed test 'xlp_magic zero'
#   at t/039_end_of_wal.pl line 312.

not ok 5 - xlp_magic zero

Where the log should say "invalid magic number 0000" I see:

2023-09-16 12:13:07.331 NZST [156812] LOG:  record with incorrect

It has to do with initial WAL position after initdb, because I get
this only on Debian, on REL_12_STABLE (with the commit listed above on
my public fix-12 branch) and only with --with-icu, but not without it,
and I can't repro it on my other local OSes.
