commit    47f514dd9a0022a04d321b627b2e991cb85396e2
Author:   Michael Paquier <michael@paquier.xyz>
Date:     Tue Jun 29 02:54:11 2021 +0000
First released in: 15.0

    Fix compilation warning in xloginsert.c
    
    This is reproducible with gcc using at least -O0.  The last checks
    validating the compression of a block could not be reached with this
    variable not set, but let's be clean.
    
    Oversight in 4035cd5, per buildfarm member lapwing.
