I'm in the process of converting some C functions written for another system
into C functions in a shared library that will be used by PostgreSQL, The
key function will be the state transition function for a user-defined
aggregate. From what I've read in the documentation:
1. the state value
variables.
If 200 users want to evaluate my aggregate at the same time how does the
backend service them? I'm only asking this out of curiosity so I won't be
too disappointed if you don't reply (because the answer is too long and
complicated, etc.).
Thanks for your reply,
Don Walker
