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, -- Jungmin Shin
