I'm fine with this. Thank you.
Looking the attched patch, I noticed that both "WAL" and "wal"
are used in similar ERROR messages. Grepping the source tree
showed me that it is always in upper case letters except in the
case it is a part of other words like variable/column/function
names or "walsender". This is the same with the word "lsn".
regards.
