Normally how??? Will the database continue accepting
other connections? Yes. Can you expect reasonable
response times from requests on those other
connections? It depends on the load of the db,
available system resources for the database, execution
plans, and other things. PostgreSQL is a multi-user
database and so functions do get executed concurrently
(sort of) when called from different connections at
the same time. Functions called within a transaction
get executed in order.
Thanks.
