Hello, I noticed that commit 06c418e163e9 uses waitLSN->mutex (a

Hello,
Note that, in the patch as posted, the column names are not
translatable. In order to be translatable, the code needs to do
something like
appendPQExpBuffer(,
" NULL AS \"%s\",\n"
" NULL AS \"%s\",\n"
" NULL AS \"%s\",\n"
Due to commit 61461a300c1c, this patch needs to be reworked.
