Hi all. I have a function that uses a "simple" select between 3 tables. There is a function argument to help choose how a WHERE clause applies. This is the code section: select * from.... [...] where case $3 when 'I' then [filter 1] when 'E' then [filter 2] when 'P' then [filter 3] else true end When the function is called with, say, parameter $3 = 'I', the funcion run in 250ms, but when there is no case involved, and i call directly "with [filter 1]" the function runs in 70ms. Looks like the CASE is doing something nasty. Any hints about this? Thanks!
