Dear people using pg_lesslog;
A very serious bug was reported on pg_lesslog. I found it's a bug in
pg_compresslog. Please do not use pg_compresslog and
pg_decompresslog until improved version is uploaded.
I strongly advise to take base backup of your database and switch to
other tools to archive WAL.
I apologize for inconvenience. I'll upload the new version ASAP.
Warmest Regards;
