Cache for query plans

Hi,

I need to implement a cache for query plans as part of my BSc thesis. Does
anybody know what happened to Karel Zak's patch?

I'm also looking for some comments & tips about how to implement a cache for
query plans and how to deal with the implementation of shared memory in
PSQL.

Greetings,
Roberto
