I have a table that I populate, select and delete the data each time the
function is run. Each time I run the function it takes longer to get the
data. In these tests, the data is the exact same every time.

I tried putting vacuum inside the function, but I got an error, cannot
run vacuum inside of function.

TRUNCATE, maybe?

Truncate won't work for me because I don't completely empty the table, I
just empty it for that user.
Each user has the table populated with his data, basically to work like
a temporary table. When the user runs a function it repopulates his
working table and then until he runs the function again he has that
dataset to work with. (I just noticed I wrote select and delete,
actually it deletes and then selects)
