At Microstate, we fixed the byte pooling code when it was still in
PG_Stream. We patched this and submitted our patch to pgsql-patches, and
it was accepted.  It did have some nasty off-by-one errors. It does not
look like the fixes we did made it into the new, separate
org.postgresql.core.BytePoolDim[12] classes.

We've been using this code on an application with many tens of thousands
of queries per day for more than a month without any problems.

I've attached the production PG_Stream.java class that we've been using.
