Postgresql is not using a cache specially for executing
UDFs, apart from only compiling the function once for each
session.

Hello,
I'm executing a query invoking a UDF.
It looks that Postgres use a cache for executing UDFs.
For example,
select a()
a is a UDF.
Excution time of above statement is different each time.
What is happening inside of the Postgres when I invoke a UDF in a query?
It is taking 200ms or 116
