In this case that may matter. One of the changes in the 8.2.6 update was:

. Improve planner's handling of LIKE/regex estimation in non-C locales (Tom)

I seem to recall this largely had to do with negated regexp matches but I
might only be remembering part of it. I would start by taking all the fixes
for known bugs before trying to diagnose a new one :)
