yes. I have done partitioning exactly you have several time in the
past...it's pretty powerful.
You can also force a reconnect when you manipulate search_path. I
personally think adding the same function to every schema is lame and
would prefer reconnect if you can fit it in. Of course, you can also
use dynamic sql everywhere but this also has drawbacks.
There has been some consensus on solving this problem...namely to have
the stored plans to be hashed out over search path (so, if your
database has 10 identical schemas, you could have up to 10 stored
plans for each function). btw, prepared statements are also an
issue.
