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 11688ms .
There is huge differences.
If a cache is used for this execution , can I turn off the cache option?
Thanks,
