Hello Everybody,
I have a question about optimization of queries which includes UDFs.
Does anybody know what the Postgres does for optimizing the queries with UDFs?
Does the Postgres query optimizer do anything special with UDFs?
Thanks,

It doesn't --- unless maybe you are considering system catalogs, in

If you can prove the contrary, let's see a test cas

I am writing a plpgsql (PostgreSQL 8.x) trigger function that should do
something on a number of records. The records are in a very simple table
with two columns - 'parent_id' and 'child_id'. A 'child' can be as well
a 'parent' to one or more children - in this case its ID appears as many
times

You could use the types' input and output functions or perhaps
