Hm. I experimented a bit and looked at the code, and I find I was not
remembering ANALYZE's behavior exactly right: it only processes all the
tables inside one transaction if you start it inside a transaction block
(ie, after BEGIN, or inside a function). If you just run it by itself
then it does a transaction per table, just like VACUUM. So I'm thinking
there's something you're not telling us about exactly how you invoke
ANALYZE.

Could you show us some of those locks (a few dozen lines from pg_locks)?
