The function private.haveaccess()'s result depends on the currently logged
in user, is it still possible to create an expression index over that
function?
// Fredrik Olsson
Hello,
All functions and operators used in an index definition must be "immutable",
that is, their results must depend only on their arguments and never on any
outside influence. ... And your function is vollatile => you can't to do
expression index.
