AFAICS the only nontrivial patch in pg_lzcompress.c between 7.4 and 8.2
is my cleanup patch here:
That's been in the tree long enough that I wouldn't have any hesitation
about back-porting it, so that all the supported versions would have
the same lzcompress code. About the only reason I can see not to do it
is that conceivably some third-party code somewhere might be calling
pglz_compress directly; in which case an API change in a minor release
would be a problem for them.
On the other hand, I remain unconvinced that this problem is severe
enough to justify much backporting work. AFAIK we've only seen one
occurence of a problem to date.
