I have a plpgsql function which is doing a loop over one table of user
data and then inserting that data in various tables. Example:
loop over user table (temp data)
insert into users1 table
insert into users2 table
etc....
end loop
Is it faster to use PREPARE for the various INSERT statements inside a
plpgsql function? Perhaps I am wrong and it does its PREPARE work
when the function is parsed.
