Initialize the interpreter only once. This fixes the crashes I've been having all the time.
Initialize the interpreter only once. This fixes the crashes I've been having all the time.

Note, in passing, that the recent move of plparrot.c to src, instead of
src/handler, doesn't fix the problem where make installs everything into the
wrong place. PostgreSQL still looks for plparrot.so in $libdir, but the
installer puts it in $libdir/src. This hasn't been failing immediately in my
case, because there's an old plparrot.so already there. That makes debugging
... less simple. :) But that's also a fix for another night.
