Sorry for the confusion. I was on vacation and didn’t look into the patch closely.

This seems to be an old bug that couldn’t be triggered before PG19 (b15c1513984 added tar support to pg_waldump). So, I
agreewith Melanie that this should be an 19 open item. 

The patch calls inflateReset() after each member finishes, allowing decompression to continue with the next member,
whichlooks like a correct fix to me.
