Re: BUG #2236: extremely slow to get unescaped bytea data

You guys are smart!

Apache was running against an old libpq.  I shutdown apache, updated
/etc/ld.so.conf with the postgres lib dir, ran ldconfig, restarted
apache, and the problem went away.

The old libpq was libpq.so.3.0 (pre-installed on machine).  The new one
is libpq.so.3.2 (installed with 8.0.1)

Sorry for the false alarm - thanks for the help.
